i just inherited this engine, some time ago i saw it run, but as i remember it would get hot and stop running, and im not sure whats up.. also im hoping that this might work in a boat project i would like to work on.... what do yall think? whats the story?

It would be good for an airboat but not for a regular boat. It was probably running too lean and overheating. Some people like to try to run engines that way and it does more harm than good.

that makes sence... you dont think that with a little ambition and some time at the lathe i can make this into a decent watercooled regular boat engine....time and tools i got, money is a different story...

Yeah, I'm in that boat too.
Honestly, an airplane motor is made for just that. A more conservative timing, smaller carb and other things that make it so they don't have the RPM and HP that boat motors have.

yea, your probably right, maby i can swap or sell this and get me another good weedwhacker motor

project5k - Just for a bit of info on an airplane engine in a boat.
My father ran the Dumas Drag"n"fly .60 size Hydro back in the 70's with a MAX - H OS 60 Airplane engine converted to a marine. He utilized Kool Klamps for cooling and redid the front by putting a flywheel on it. Had the standard exhaust running out the side of the boat.
My brother said it ran great although I was to young to see it go. I still have this engine.
He then converted to the OPS .60 Which I have just rebuilt and put in my new Hydro
