Ed,

There are a whole lot of three cylinder outboards without camshafts out
there, but they are all 2-stroke. Even if you are planing to make it a
single acting uniflow, you may have trouble with the exhaust port height.

Given that you won't have to cool it, you could make this work by
sleaving the it so it can still use a stock piston. Then you can put
the exhaust pots where you want them and then you only need to make a
new cylinder head and camshaft pair and linking drive.

Good Luck
