Size matters.
With propane in a tank that is not an easy fill the smaller OB will be the best conversion
10hp costs a Gal of gas , even with a modern propane setup that might come close that is a bunch of fuel for a large engine.
A yachtty's 4 or 6 hp run at modest rpm will go thru a 20lb (4.2 gal) cylinder nice and slowly.
A 50 might empty it in a single hour.
One huge advantage of propane is the fuel is so clean that the gas engines (at least in noisemakers) get diesel service hours before needing replacement/rebuild.
Due to the lubrication issue , I would think a 4 stroke would be required.
