The weekend was good.
I picked up ( literally out of a basement of a very old house) a St Lawrence.
Here is a video of it when I got it back to the shop.
http://www.youtube.com/watch?v=4KUZfnP5OeA
The Serial No is 1179 . It sat for 40 years in the basement. It was never run in all that time. It came out of a 30 ft fantail launch that had been converted to sail. The engine was the auxiliary power.
There is a remnant of nickel plating on one of the heads.
The muffler has "No 3" in raised letters on one for the end plates. The muffler played host to mice for a while - mercifully they did not get into the engine. The insides of the muffler were rusted out but the end plates and body are OK.
Anyone know what the insides were like?
The gearbox is a GIES not a Detroit as mentioned in the video.
Here is a picture of the front of the engine - the flywheel is a bit strange for a St Lawrence - a 2-holer, rather than spokes.
Here is a close up of the tag.
I'll be building a cylinder ignition box for it and maybe in a couple of weeks I'll try firing it up.

Thanks Miro. Does the flywheel look original? I can't get your video on my dial-up.
Let's see some pictures from Gravenhurst! I've got some here that I'll try to load later in the week. |

Nice find Miro, flywheel looks smaller than normal, wonder if there was a clearance problem? |

Miro, finding that old timer definately makes for a GOOD weekend !
Added # 1179 to the St Lawrence Engine list!
1918 would be a pretty close date of mfgr !
This is the updated St Lawrence Engine List, if any info, wording, spelling needs changing or any engines not listed, Please post here or to my email.

By coincidence, I came across this ad today. Unlikely there is any connection between the two companies other than the 'St. lawrence' name. Did this St. Lawrence also build small inboards in the earlier part of the century?

I like your engine Miro. Thanks for posting the video and photos. The can style mufflers for the stationary Detroit's had two different size tubes inside the canister, one inside the other and a spacer plate at one end. Does the cast ends have round or circled grooves on the inside to hold tubes? |

HI all,
Yes the end plates of the muffler have grooves to hold the ( now rotted) perforated tubes. Any idea how long the tubes should be?
I've been Internet-less for the past week -
But I have built a 2 coil ignition box for the engine and maybe this coming week I'll have it fired up . Hopefully a video too.
Richard D - check the name in the entry - I think you fat-fingered it :-} FOREST
I very much appreciate all of your work Richard -
It would appear that the engine was re-built, but not at the factory, prior to being installed in the sail boat conversion . But it was never run much in the sail boat - so I think I've got a good one here. The re-build was done over 40 years ago.
Much progress was made on the fan tail launch over the past week. The difficult parts eg the repair of the bow stem and the re-build of the keel and stern post were done.
Now, onto the the easier parts - the planking repairs and then the CPES treatment.
More videos on that coming up too.

Richard,
In the notes section you can add alum piston and tag to mine
Searcher,
Not sure if St Lawrence actually made any automotive style engines but they did make conversion kits for Ford engines to include the Model "T" and flathead V8s.

Miro,
I'm not sure how your muffler is made inside. The stationary Detroit mufflers that looked close to yours actually had another baffle plate inside that set up about a inch or two from the bottom plate. This inner round plate had round groove for the inner tube also had some holes. Wished I would have taken some photos of the muffler I reproduced for my twin cylinder Detroit. Maybe the scan below will help. Looking at the scan below the inner baffle sets over the round boss on the bottom plate. Then the inner tube sets on the baffle plate in a groove. Detroit muffler has no perforated tubes as you can see. All the holes are in the baffle plate and top plate.
I'm going to guess that your inner tube is probably about as long as your outer tube. A little bit of measuring and calculating using your outer tube and groove depths and I'm sure you will figure it out the length you need.

Miro,
The heads have obviously been off going by the head fasteners. From the priming cup location it appears from what we have seen on existing engines that your head... OOOPS I mean the heads on your engine may be on 180 deg off. When and if you pull the heads can you confirm please? What I am looking to see is if there were any engines built with the priming cup located other than the forward port side of the head.
Thanks in advance

Ernie, I have about 175 photos of St Lawrence engs,going through them one by one found 10 engs with primers not in the front port position. Doesn't mean much as each head would have to be looked at to see if water ports line up ? All catalog and printed material show front port location!
Something to look at !
