Hello everyone,

I've just aquired a Gray Marine Engine Model 115 / Eng#G7380 w/Venith Carb tag#10870 Do I need any other information to determine displacement, hp, approximate age, etc? I have photos if needed. Thank you!
 
I'm guessing that is a flat head six that is probably based on the 226 CID Continental industrial engine. you should be able to find "226" cast into the block near the oil pan flange, probably under about where the oil pump is.
At least this is the case with the Gray 109. I suspect the 115 is about the same engine with maybe a bigger carburetor.
 
Hi,
You have a 1950's 224 cu.in engine with zenith 63m2e12 spec10870 carb also used on lugger exp6-226 &luggerexp6-224.
