Is that an order, Richard? OK!
We just got another number off a friend's engine today. S/N is 7517, Model XBE. Looks like brass tag.

Here is an image of a St Lawrence advertisement with what looks like a starter wheel. The advertisement states "WRITE FOR OUR 1913 CATALOGUE".
Also a image of the engine without transmission or BOSCH magneto.
The starter must have an overriding clutch at the crankshaft sprocket, any thoughts?

I guess that would be the 'lightweight' engine in the photograph? Looks like aluminum base and manifolds. Interesting that the tag is out on the exhaust.
Taking a closer look, it also appears that the ignition is geared off the side of the crankshaft rather than directly above with a bevel gear.
Likely has a ratchet type clutch behind the flywheel.
Has anyone claimed fame to the nice old 3 cylinder that was just sold on ebay? |

JB, you asked awhile back about the drip oiler. I believe that you're right, the cap screws near the top of the block would be the mounting points to hold the oiler. The pipe plugs just above and inside the inspection plates would be removed to accommodate the oil lines into the crank.

I believe the three cylinder belongs to Steve Fox. It is a lightweight racing version of a St Lawrence engine. Steve has some great engines and is very knowledgeable Canadian engines. |

This is my St Lawrence serial 5812, Interesting because it was my wife's grandfathers. Always in fresh water, on Kootenay Lake BC Canada. I restored it, it made it into the house, but still hasn't made the living room. Derek |

Thanks for the posting, Photo filed and Serial # entered in our St Lawrence Engines list.
A calculated guess of the year Mfgrd would be late 1920's ?

St Lawrence offered a cottage pump in what is thought to be their 1932 and 1934 catalogues. Here is an image of the catalogue page and an outfit ownwd by Ron Jelley. The engine is model XA with cooling water pump removed as a TEE off the main pump supplied engine cooling water.
Engine is serial 5485.
Ron has been trying to determine how fuel contained in the base was elevated to the carburetor as there is no evidence of a fuel pump. Any thoughts ??

Possibly base pressure through a check valve to pressurize the tank, like the old Evinrude and Johnson double hose systems. |

Barry, looks like they're still showing the marine water pump on the engine, with the inlet coming from the large pump. Slightly overkill. Maybe the company artist who sketched the picture was just having a seniors moment...
Could be pressure in the tank to suppy the fuel. Are there any of these cottage pumps that came out of a boathouse complete, or have any been restored to running? |

Here is a link to the stlawrenceengines.ca discussion about the cottage pumps and fuel delivery issue.

I am the owner of engine no. 5760 that you have listed under my username of “toomitch” from the St. Lawrence web site. This summer I finished rebuilding it and have some information to add to your listing. It is a:
-single cylinder,
-cast iron piston (3 ½” bore, 4” stroke),
-½” NPT spark plug,
-no baffle in the transfer port,
-rectangular brass tag has serial number without model identification,
-single flange water pump with 2 piece eccentric strap (old style),
-a one piece wet manifold in the round style shape,
-and a flywheel that measures 14” diameter and 1 7/8” face width.
The head and the outer rim of the flywheel showed signs of nickel plating. I asked to have the head nickel plated, but the company mistakenly chromed it. Haven’t started this engine yet, collecting the electrical parts now.
Can't get this photo to move, will try later.
_______________________________________
This engine is serial number 5153:
-twin cylinder
-aluminum piston (3 ¼” bore, 3 ½” stroke)
-1/2” NPT spark plug
-no baffle in the transfer port
-rectangular brass tag has serial number without model identification
-single flange water pump with 2 piece eccentric strap (old style)
-a one piece wet manifold
-and a flywheel that measures 14” diameter and 1 ½” face width
This engine also shows remnants of nickel plating on the heads and the outer rim of the flywheel. This engine will be this winters project.
________________________________________
This engine is serial number 7764:
-single cylinder
-aluminum piston (3 ½” bore, 4” stroke)
-18 mm spark plug
-access plate to baffle in the transfer port
-rectangular aluminum tag has serial number and model identification XBE
-water pump with 2 flanges and one piece eccentric strap (new style)
-the manifold is missing but would be a one piece and wet
-and a flywheel with a ring gear that measures 13” diameter and 1 5/8” face width.
______________________________________
This engine is serial number 7961:
-single cylinder
-aluminum piston (3 ¼” bore, 3 ½” stroke)
-18 mm spark plug
-access plate to baffle in transfer port
-rectangular aluminum tag has serial number and model identification XA
-water pump with 2 flanges and one piece eccentric strap (new style)
-a one piece wet manifold in the round style shape
-and a flywheel that measures 12” diameter and 1 ½” face width.
___________________________________
This engine is serial number 7939, and just has the cylinder, crankshaft, and a seized piston:
-single cylinder
-aluminum piston (3 ¼” bore)
-access plate to baffle in transfer port
-rectangular aluminum tag has serial number and model identification XAE
-the water pump would have 2 flanges
-manifold would be wet and one piece.
Not installed, but with this engine came a flywheel that looks like the one by Owen Bosma in an earlier post. It has 4 teardrop cut outs, a ring gear, and measures 12 5/8” diameter and 1 3/16” face width. I was told by a senior Dispro member that it is thought that these flywheels were used at the very end of production. Maybe when assembling engines from stock parts supply after 1950 they ran out of flywheels and still had more parts to assemble, and came up with these flywheels to complete the last of the engines. No mention of where they would have come from.
____________________________________
It has been mentioned often that after 1934, St. Lawrence used aluminum pistons. This probably comes from a reprint of the 1934 catalog that many people have and quote from. I recently bought a 1932 catalog, and it says all one and 2 cylinder engines have aluminum pistons and light steel connecting rods, so we can safely move the date back to at least 1932.
St. Lawrence used Ford Model T’s, Model A’s, Fordson tractor, and flat head Ford V8 engines for marine conversion. I don’t know the starting dates for Model T’s & Model A’s, but from these 2 catalogs we find the first use of Fordson engines in 1926 and the first use of Ford V8’s to be 1934. St. Lawrence also started to manufacture their own reverse gears in 1934, using Paragon reverse gears in the 1932 catalog. Glad to see all the work you are doing to help date my favourite engines, thanks,
Al Cleary. |

Thanks for the posting your engines, all photos are filed and all serial numbers added to our St Lawrence Engines list.
Some interesting info here, The 1932 catalog lists aluminum pistons ! your 5153 # engine above would seem to date even further back around mid 1920's and has the aluminum pistons ??
Teardrop flywheel is going to be a continued discussion >
