I'm thinking about getting rid of my old Force 50 on the little boat and

have enough weight in the boat that every pony under the cowling makes a
difference.




15" shaft length or 20" shaft length?

If you are going to limit yourself to 50hp, look for an example of the
J/E 3 cylinder loop-charged engine of a few years ago... should produce
at least 50hp at the prop, they are a de-rated version of the 70hp
looper. They are only available in the 20" shaft, though.

For a 15" model, I'd try to get away with the 60hp Mercury Bigfoot
version, the highest hp currently/recently available in a short shaft.
