Can someone help me with the HP of a Titusville Olin? It has 54" flywheels, 9" bore and 16" stroke. Thanks in advance Chris

I would guess it is a 15 HP. There was an earlier post by 65vette396 that said his 15 hp had a 9 1/2 inch bore. I have a 20 that has a 10 1/2 inch bore with a 16 inch stroke. The only thing that seems surprising to me is that your flywheels are so small. Mine are 63 inches in diameter and have a 6 inch face, surprised to see that much of a difference in flywheels for just 5 hp more.

Thanks Ray, the flywheels are also heavy, like the rim is I'd guess about 2 inches thick and 4 inches wide.

I too have a 20 with the same bore & stroke as Ray's.
My flywheels are also 6" wide, however they are 68" diameter.
Don't have any hard Olin data handy, but looking at other mfg's
info from the same time-frame, [bore/stroke flywheel diameter]
indicates it could be in the 12 hp range. Perhaps someone can
find and post Olin spec sheets that can answer the question.

I have two catalogs that list the Olin but neither show any specs that help much in identification. One just lists the horsepowers available as 10, 15, 20, 25, 30 and 35, while the other lists shipping weights.

What does it list as shipping weight for a 20 Ray? Bill Klein

This is from a 1918 Continental Supply Co catalog for Olin Engines

10 HP 9 x 12 3300 LBS
15 HP 9 1/2 x 14 4200 LBS
20 HP 10 1/2 x 16 6200 LBS
25 HP 11 x 18 7200 LBS
30 HP 12 x 19 8000 LBS
35 HP 12 1/2 x 20 8200 LBS

Hope this helps to figure out the HP of your engine.

My 1908 National Supply catalog numbers were very close to Roger's except the 35 hp It is listed as 10,300 pounds. The 20 hp for example is listed at 6145 vs 6200 for Roger's catalog. Wow I would LOVE to have a 35 HP Olin!!! Anyone know of one that has survived?

I have a 35 HP Olin (see attachment)
12 1/2 x 20 cylinder
6' x 7" flywheels

1st photo shows engine before being hauled home. From the Klondike area near Bradford, PA.
2nd photo 30 or 35 HP Titusville Olin. Exact seup that my 35 was taken out of but this engine is not the one I have. In the picture at the end of the foundation you can see SPOCO. South Penn became part of Pennzoil.
3rd photo is of a South Penn Oil Company octagon pumping power building.
