Greetings All, I have a 12 foot aluminum boat that is rated for a 10 HP max motor. I do have a 10 hp outboard but bone on bone joints in both wrists makes it really painful to put the motor on. For years I have been thinking about various schemes to put in a liquid cooled 4 stroke inboard. One idea is to use a conventional air cooled flat head motor that's been modified with a water jacket. I told Harold Vordos about this idea and he had done it and it worked well. I mean the liquid cooling conversion. He even had done it with a motor that was very close to a 7 hp motor that I have and was considering. I have also thought about using a 125 to 250 cc motorcycle motor. But these are expensive and rev higher. I have several reasons for wanting to do this project. Mostly I want a quiet power plant and a liquid cooled engine inside some sort of housing seems like it would fit the bill. I want 4 stroke mainly because I'm tired of putting oil in the water. I also want reverse and am not sure what is the best way, at least for me. The plan is to use a prop shaft that pierces the bottom of the boat and a rudder. So the motor would be inboard as would the reversing gear. Money is tight so don't suggest a Crosley engine. If I could even find one for sale. Any thoughts? Thanks, Eric
