I found this St. Lawrence to be for sale and I will get to see it in a couple of days. Is the $750.00 asking price in line for such an engine or too much to pay? The serial number is 5441. How old is it?Here are some pictures:

Dennis, there's a long discussion on here about the St Lawrence engines if you search it. This is the later one piece manifold, don't remember when they changed. There were some serial # to date guesses there also. |

I pickrd up the St-Lawrence this afternoon. It has awsume compression! It features a Monarch brass carb and the flywheel is only 14 inches in diameter. Is this the smallest size engine St Lawrence made?

Denis,
Go to this site www.goslowboat.com
Image at left is same engine as yours.
Image at right is smallest St Lawrence engine.
Note position of priming cup. Head on your engine is incorrectly positioned. Should be positioned 90 degrees clockwise. |

About a month ago there was a St. Lawrence for sale in Little Hr., Newfoundland. I understand it was brought from Hamilton, Ont. and in original crate. Asking $3,500. |

Thanks for this info bcm! The St Lawrence being my only engine I can carry in my arms, made me think it could have been the smallest, but now I know it's not 
Looking at: www.goslowboat.com I see these St Lawrence engines were restored and painted red in one case and green for the other 2. Mine has lots of black paint left but I can't tell if it left the Brockville factory in black or if a new coat of black paint was applied to this engine 50 or 60 years ago.
Can anyone tell me the color a St Lawrence should be. If black is the original color I will leave it alone; if not I will repaint it to the proper colors and polish the brass.
Thanks everyone!

Denis,
I would say that your engine was likely repainted since it looks like there is black paint on the water pump. But yes, they did come out painted black from the factory as well - often with nickel on the head and flywheel rim.
Hope that doesn't muddy the waters...

Dennis, the engine looks great, but it would be wise to remove the head and check to see if it is installed wrong. The primer cup is usually on the other side, front. These heads have a spill tube cast into them, water fills the head and spills over into a cast passage that mates with the outlet to the exhaust. If the head is in the wrong position water will never fill the head and it will run hot. |

I'm confused! Bcm said that the head was on wrong when I got the engine last week. I took the head off and turned the head 90 degrees clockwise as seen in the latest pictures. Now Jb you still think the head is on wrong 
There are only 4 positions the head can go on. 3 wrong ways and one correct way???

Denis, looks like you rotated it 180, should have went 90 degrees. When the head is off, match the small port over the exhaust with the one in the head, all of the engines I've seen had the primer on the fore port side, yours may be an exception. |

Wow I read all the mail re the old engines and am so envious that you have so many . Would love to import one as we have very few old motors. I have ablaxland twin but would love an older single siylinder wonder what the cost of shipping is . Has any one any idea and where do I look to find one .

These heads are on correct.
As JB says forward port side
Hope this helps
Ernie
Yes the aft cylinder has an incorrect priming cup.

I popped the head off on the St-Lawrence and took these pictures:
http://buzzcoil.brinkster.net/St-Lawrence/stl5441o.jpg
http://buzzcoil.brinkster.net/St-Lawrence/stl5441p.jpg
http://buzzcoil.brinkster.net/St-Lawrence/stl5441q.jpg
It now seems evident to me that there is only one position where the hole passages on the head matches those on the main casting. Interestingly, before a previous removal of the head someone had taken the time to make punch marks on the head and on the main casting to indicate how the head was to be put back on. Unfortunately he did not put the punch marks in the right place.

Denis, does the primer end up in the normal spot? |

JB, you tell me if the primer cup is in the normal spot. I don't know what should be normal. Here is the latest picture I just took after putting the head back on:
http://buzzcoil.brinkster.net/St-Lawrence/stl5441r2.jpg
I've indicated the 4 possible positions the head could go on. No.1 shows location of priming cup after I lined up the holes in the water passages. No.2 is the position the priming cup was in when I first got the engine. No. 3 and No. 4 are two other possibilities.

Denis, #1 is correct. Did the head fit better? I thought the holes weren't symetrical, you had to force it on wrong. |

The stud holes in the head are of equal distance as the head slips on just as easy in all positions.

Denis, if it is any consolation to yoju, the 2 cylinder St Lawrence that I got a couple of years ago, had the same issue about the position of the head. Even though it ran, I didn't run it for long and so avoided a bad result.
Fortunately, one of the boys on the OME web site, gave the same info that you received and I now have a good St Lawrence.

Bought a one cylinder St. Lawrence engine from a fellow near Elgin On. for $100.No serial # but it has a cast iron piston and solid bronze connecting rod.
It came with a cast iron muffler and bronze exhaust through hull.

Hello,
Looks like this is an older conversation but if it's still going I have questions. I have a marine engine with a no of 6642. I haven't been able to find much info about it. If anyone knows anything about this model that would be great. Thanks  |

Looks like a Model A Ford engine
At least that is what the distributor is.
Not sure on the cylinder head. |

It's called a Type A St.Lawrence, using a Ford Model A block. Opposite to the cars, the shaft/trans. drives off the small end of the crank. I haven't seen it in the literature pictures yet.
