I really wish I knew, I bought the engine last year, just rebuilt after my 225 rude shredded the splines in the crankshaft. That setup also only ran around 38 with just myself on a glassy day. I agree I should at least be in the mid 40's. Two GPS's told the same story, pig.

Its gotta be the prop and the prop is in good shape stainless, no dings or chips. Maybe not the pitch but the diameter. I wish I could rent a prop to get the right combination of diameter and pitch.

I gotta say it is nice being able to stand her up in 3-5's in the inlet with a low wave period.
