Ernie had a late mfgrd engine with electric start flywheel that had the teardrop design.
J.B. mentioned the teardrop flywheels like the VICTOR engines !
This is just talking out loud at this point!
"Victor" plugged into my data base and 8 manufacturers names come up, two of which may be relevant.
1.Etherington Gas Engines Ltd., Shelburne,Nova Scotia. Trade Name of engines- Victor, Etherington, Clarence and Bessie -- this I believe is the VICTOR with the teardrop flywheels.
2.Atkinson & Bower, Etherington\Shelburne, Nova Scotia and the successors to Etherington Gas Engines Ltd in 1946.
Possible that st Lawrence purchased flywheels from this company ? or was a source of replacements in the late 1940's and thereafter ??
I have a note that says one of these teardrop engines was displayed at 2008 Mystic show but I can't find the photo ?

Richard:
I removed both heads on engine s/n 5153 and double checked, they are both aluminum pistons. Also noted that the flywheel seems light (14” X 1 ½”) compared to some of the other twins, as might be expected with aluminum pistons. I also see that my other entry s/n 5760 has a higher serial number but with a cast iron piston???
Owen Bosma’s engine with the teardrop flywheel looked a lot like my entry, s/n 7961, with the red and blue colour scheme. I phoned him and found that his engine and mine, plus my s/n 7939 with the teardrop flywheel all originated from the same man, Mr. Cole from Picton Ontario area. Could have come from St. Lawrence or maybe just flywheels that Mr. Cole had around. Need more examples to draw a safe conclusion.

The Atkinson & Bower flywheels that I've seen are a lot heavier than these, and quite a different design. They do have teardrops though. |

I guess That St Lawrence Mfgrd the light weight engs Right along with the Heavier engines for many yrs.The 5153 # engine does seem to go back into the 1920's ?
If Mr Cole is still around maybe a call to him would solve this flywheel mystery ?
Blair
The Ethrington flywheels that I have seen in photos and catalog shots are indeed much heavier than these St Lawrence examples ?

Mr. Dave Cole is no longer with us, his collection was auctioned of several years ago. A lot of knowledge went to the grave with him. He lived in the South Bay area of Prince Edward County. He served as curator of the Marine Museum at South Bay for many years.

Hello All, It has been a busy few months and I am just getting back to checking my favourite computer sites and was very surprised to see all the St Lawrence postings. I acquired this unusual 2 cylinder this summer and after talking with Barry thought I'd post it to see if any one has any info on it.
It is a 2 Cylinder, Serial # 1118, 3 1/2" by 4"
It has a 2 part manifold, but is has no way to drain the exhaust manifold. There is a screw on the back outlet to regulate flow from the back cylinder. There is a second screw near the water outlet that doesn't seem to do anything.
An adapter (1 1/4" pipe thread) seals off water at the back of the manifold.
The flywheel is 15 3/4" by 2" thick. This engine has not one but 2 tags on it. There is a 2" round tag on the top of the timer and a rectangular tag 4" by 1 1/4" on the head cylinder with the serial # 1118
The heads appear to be aluminum and the spark plug is 1/2" pipe thread. The priming cups are marked with Lunkenhiemer No 00 R. The water pump is a Brass Lobee. There is a gear pump located on the timer shaft and the grease cups on the main bearing are steal. It has cast brass guards over the timing gears and an extra lug on rear bearing to bolt the guards to.
What's left of the original paint appears to be dark green and on each of the cylinders is something I have never encountered before. There is an "F" embossed in a 3/4" circle cast right into the back of the cylinders.
Also there is a slight projection on the top of each cylinder that seems to be there just to center the head gasket?
It is quite an interesting find and I would appreciate any opinions about it. I also have 6 more St Lawrence engines - one more 2 cylinder and 5 single cylinders, hopefully I'll get them on line in the near future as well.

Great photos. I love looking at all these old components, even though i may not be dealing with these particular engines!
I spend ages studying parts - the way castings are designed etc.
Thanks for posting pics! |

Here is an image from what I believe is 1913 St Lawrence catalogue. It looks like Phil's engine. There should be holes for the oiler connections. All the other holes appear to match the catalogue image.
The same catalogue shows a "special lightweight Motor For 1911 ( reference my post #77 and #93) with special nickel aluminum alloy heads" . Looks like the aluminum heads were used on Phil's engine.

Here are catalogue pages from the 1913? Catalogue. Notice the parts picture shows both rotary and lever timers, both gear and piston water pumps, exhaust manifold with access plate, straight in supply manifold and St Lawrence carburetor.
Also a composite image of three similar engines. I seems the use of rotary and lever timers was optional. It is also possible that St Lawrence carbs were supplied with a straight in manifold, possibly later changed to Scheblers . The offset inlet manifold on Phil G’s engine may have been used for Scheblers to lower inlet connection.
The access plate in the exhaust manifold is a mystery, Phil would you confirm if there is a plate in your engines exhaust like the other two engines.
These differences may help to confirm dates.

Phil,
Good work on the photos with close-ups. Looking forward to hearing about the other ones when you get a chance.
What do we make of the "F" in the block casting? Is there a chance that St.L farmed out their foundry work to another foundry during the war? |

Phil,
The image of your two cylinder engine shows what may be a reverse gear. Here is an image of a catalogue page with a note that " St Lawrence reverse gears were designed by us in 1917". Would you check if there is a reverse gear attached to your engine and if it is as illustrated by the catalogue page.
Owen, I suspect the electric starter was added in the 1940's when these were avaiable for XB engines, same diameter flywwheel as the twin.

Well, over 60 engines on the list in such a short period of time. I'm sure that there will be more surface, especially as we move into next years show and boating season.
I just wanted to say a big 'thank you' to everyone who shared. Especially to Richard who has a special gift with this data management stuff and seems to be able to keep all the details in order.
I know I've learned a lot through this discussion.
Thanks again, and keep the info coming.

Hello Everyone, thank you for all the input on #1118. I apologize for not responding immediately, I do not own my own computer so it limits my time on-line. I will try to answer all of the questions that were asked and pose a few of my own.
First: there are no holes to connect an oiler to the cylinder, but on close inspection I did find a plugged up hole for an oil line on the rear cylinder only. Second: there is no removable access plate on the manifold. Third: the reverse gear is made by Bulldog, Model A, from Detroit. Fourth: the embossed letter "F" in the cylinder? - Blair had an interesting thought about it being war time. Has anyone seen this on any other St Lawrence? Could WW1 also be the reason for the less expensive steel grease cups instead of the usual brass? I finally have managed to get the pistons out of the cylinders, there is a faint #10 on the top but they are not oversize as they measure exactly 3 1/2. The pistons do have a section that is turned undersize for the wrist pin down toward the skirt for about 1 1/2". (see image) Is this normal? I can't remember ever seeing this feature before. I have also discovered the 2 bolts for holding the center bearing together are 1/2" by 12 threads per inch, but the 3/8 by 16 threads per inch holding the bearing plates on seem to be undersize? Is there a special size designation for these, modern bolts are very very tight in the holes! I am wondering if anyone can tell me where Lobee pumps come from, I have another 2 cylinder - currently unidentified - with one of these pumps on it. Perhaps the location of the pump maker can help me narrow down the engine origin.
PS: I have noticed that my electric start 1 cylinder St Lawrence also has the teardrop flywheel, but a Zenith carb. Thanks for all the response and info, Phil |

The undersized section of the piston looks like it would be to collect oil for the wrist pin. Usually a 3 1/2" bore would have a piston a few thousandths undersize, is the bore 3 1/2" or slightly larger? It wasn't uncommon for manufacturers to match up slight overbores with oversized pistons. Auto manufacturers did this, at one time you could order .001, .002 and .003 over pistons. I guess CNC equipment has sent this by the wayside. I checked on a piston for a 502 Chevy in an airboat, only available in std and .030, $200 each. |

Back from the Thanksgiving Holiday, And a lot to comment on here!
Phil G. - Thanks for posting.
Serial # 1118 added to our St Lawrence Engines list- All photos filed ( a note here, I file all photos so that in future someone has a question maybe one of these pics will be worth a thousand words)
The F casting letter will probably be a foundry designation, Engine Companies that mfgrd way many more engs than St Lawrence outsourced their castings and with the small facilities and work force they had just machining and assembling would seem to be task enough ??
Lobee Pump ad
There was only 4 or 5 rotary pump mfgrs for small marine engs in these early yrs and probably won't help with eng ID ?-- Post photos of your unknown is best chance to put a name on it !
Bull Dog Reverse Gear
__
Owen - I added your friends twin to our list, I can add his name in the owners column if he wishes let me know ?
__
Barry- Really Good to have the dated catalog photos for reference. As to the reverse gear I would think that that was also outsourced to one of the specialty gear mfgrs ? I keep info on reverse gears in my data base i'll see what looks similar, the Bull Dog may be it, with a different designed top case ?
__
Ernie- Thanks for photos of this twin after all It was Dick's question " Are you collecting St Lawrence Serial Numbers" that got the flywheels spinning initially for this project !! THANKS Dick Day.
__
Blair-- I Echo your BIG THANKS to everyone that has shared - We collectively here have in a couple of weeks assembled the basic pattern of serial numbers,and can interpolate within a few years as to the mfg date of most of our engines, the technical design differences,and many of the optional types of engines mfgd by St Lawrence.
Enthusiasm, information and some fun, part of what a great hobbie is all about!
About 11 more engs that I know of right now to get on the list when everyone gets around to posting or emailing the info !

Hello everyone, unfortunatly I do not have a date for this St Lawrence brochure, but it does have some interesting points. If you look carefully on the picture of the electric starts you can see it has the tear drop flywheel. Also on my original copy someone pencilled in the original purchase prices, they are as follows: XAE $275, XBE $300, XA $205, XB $235, XC $318, XD $390! |

Yes, I am the happy new owner! The engine is in good shape except for a few minor issues. No SN found, no tag. Bore/Stroke is 3.5X4". More info will be posted as work progresses. It's the choice to power a 26 foot cypress bateau. |

Guys,
Not to be a party pooper... but...
Take a good look at the pic in the electric start add. That engine has a 6 spoke flywheel.
Also the teardrop flywheels were only 4 holes not 6.
Or am I missing something? I assume we are talking about the add posted by Philg on Sunday the 7th with his comments below the add |

Richard,
The Atlantic "is the only engine with a heart", that was part of their advertising. The holes in the flywheels on Atlantics are heart shaped.
These holes about which you are talking are more like tear drops or rain drops.

St Lawrence did not do any of their own castings. They had a relatively small "factory" during the good years (1905-1917) which consisted of an assembly bench and several machine tools, lathes, milling machines and so on. They made their own wood molds (I have several or rather I am looking after several of them) and farmed out the work to Frost & Woods, a farm equipment and tractor manufacturer located in Smith's Falls, Ontario (55 miles or so away from Brockville) The F on the casting may be Frost & Woods. Later they apparently also had some casting work done by H. Imbleau & Sons of Arnprior, which was ( and still is) primarily a storm sewer grate foundry in Renfrew, Ontario. Non-engine casting for boat hardware (which they sold as a side line) such as chocks, cleats, and so on was done by the Ontario Iron Works in Gananoque, Ontario. |

This small engine belongs to a friend living less then 10 miles from Brockville , his father (now past on) always said that this engine was cast by James Smart Manufacturing and machined by StLawrence
looks to me that there might have been a collaboration between Smarts and StLawernce to build a utility engine. This engine is early, note the 1/2 inch pipe spark plug. This also makes me wonder how much casting work done by Smarts for Stlawrence.

Aha! This is what I was wondering with my previous question: whether James Smart & Co./Smart Bros. foundry might have done the work. Their mark is a "G" in a 'horizontal' diamond. They were also heavily involved in forging work as well and steel and iron tool making generally. |

I asked this question of a few people connected with or interested in St Lawrence history. In spite of Smart's foundry being almost next door apparently St L did not have any of their castings done there. Smart's was a big operation and the small orders from St L may not have been worth their trouble or time. St L did a lot of service work on Smart's machine tools though, which was a side business. |

}Hello everyone, I have finally managed to catalogue my other St Lawrence engines for posting. This is my XAE, but unfortunately it has no tag and therefore no serial #. It does have the 12.5" fly with the 4 hole tear drops. It's an electric start and has an aluminum piston. It has a Zenith carb on it with an unusual brass piece - any ideas? The spark plug is 1/2" pipe thread and the grease cups have "D" style handle I have never seen before - does anyone else have these? It has the new style water pump and there is an inspection port on the transfer. |

It has a 3 1/4" bore and the same raised centering ring as on #1118. It does have the old style water pump and it would have a 2 piece manifold - except that it is missing! I am all so missing the rod and piston for this engine - any chance some one has spare parts? |

THANKS for photos and posting, I added all engines to our list and filed the photos.
The two engines that have no Serial # I listed at bottom of list in an "UNKNOWN" Catagory as ERNIE suggested until we can find out where to place them on the list !
Will post updated list tomorrow

Information about post WW2 St Lawrence engines.
According to information contained in the “The Greatest Little Motor Boat Afloat - The Legendary Disappearing propeller Boat” Greavette Boats Limited who were the Dispro builder starting 1945 used the St Lawrence model XAE (3 HP electric start) and this continued until 1950 when the Coventry Victor Midget was adopted.
About 200 Dispros built during this period were fitted with St Lawrence engines, presumably all XAEs , with serial numbers between 7540 & 7950 so if the serial numbers were applied consecutively then about 200 engines were supplied for other than Dispro installation during this period.
Here is an excerpt from this book that explains the switch to Zenith carburetors, note Zenith carburetor on Phil’s engine shown in his post #13.
John Thomson is owner of 1950 Dispro with St Lawrence XAE serial 7851 with original Zenith carb.
One of my engines an XA, hand start, serial number 7959 was purchased new by my father in 1951 with a Zenith carb,. I changed to a Schebler D. John still uses the Zenith.
It is thought that St Lawrence ceased manufacturing parts in 1947 then continued to assemble engines from in stock parts. It has been suggested that the tear drop flywheels were substituted when the spoke style ran out. All but one tear drop flywheel engine fits this speculation.
The engine pictured in Owen Bosma’s Nov 23 post in St Lawrence Part I has an old style cylinder casting with tear drop flywheel and very old name tag. One can only guess that the original flywheel was replaced.

The timer determines which direction it will start and run. If you have the timer straight up it should be 0 advance in either direction, engine should start in the direction the flywheel is pulled. Check to be sure the piston is up on the front cylinder and firing, then 1/2 rotation the back cylinder should be up and firing when the timer is straight up, be sure nothing is grounding the ignition and it only fires when the timer is up and pistons are up. If you move the timer away from the direction you are pulling the flywheel, at about a 2 or 10 O:clock position, pulling the flywheel against it should cause it to bounce start in the other direction, it will take the flywheel out of your hand. |

Haven't had much opportunity to post lately, but I went to look at some stuff in a barn and you won't believe what I found, I can hardly believe it myself. This 3 cylinder St Lawrence is had no serial # on the tag, is missing the brass gear covers and had been retro fitted with a delco remy distrubter. My luck was really in, managed to find the original St L. carb and 3 drip oiler. If the snow ever goes away I'm heading back for more searching!!

That is a real find !
This engine with the large
name plate on the manifold dates 1905-09 ca. It is not only very rare to find a 3 cylinder but this is the oldest one on our records !
Look at the flywheel outer rim for any serial numbers, like these -

Phil,
Great find! Is it a 9 or 12hp? Nice to see another original carb surface too.
I assume it has the small rectangle tag rather than the round tag?? I doubt if you'll find a serial number anywhere, but let us know if you do. I believe that the one Richard posted above must be an owner's inventory number rather than a St.Lawrence serial number.
The earliest engines have water pipes exiting the heads and dumping into the top of the exhaust manifold. The later engines with the oval plate on the exhaust had round tags. So I would think that this engine is 2nd generation, maybe 1906-1908??
Thanks for sharing,
Blai |

Blair, the engine is a 9HP, as you can see it does have the small brass tag but with no serial number, I cleaned the flywheel but did not find any number there either. The embossed oval tag is on the manifold- does anybody know if these oval tags are removable? |

In regards to the "serial" numbers on the flywheel that Richard posted - I now own that engine, when I bought it I was told it referenced 07 month, 17th day and engine #245. No one knows who put the markings on it. Upon looking closer at it I discovered more marks - directly above the keyway (possibly top dead centre) are two circles with the #2 in them and then 180 degrees over directly opposite the keyway are the same marks - has anyone seen anything similar?

Phil,
I checked our old twin with the water exits from the head and found no timing marks on the flywheel face. No help there. |
