I think that motor should be propped for 4600 RPM. With a 21P prop, I'd guess low 50's MPH.

I owned a 1988 Wellcraft with the same setup, it ran 56GPS. Light on fuel. Never played with the prop or anything.

Sounds spot on. A Mirage+ 21" would be the prop to try.

Search for Kidnova's posts.
He has a 23 Nova that went low 70's with a ZZ502. He is now over 80mph, but obviously a handful and obviously much more of a motor than a ZZ502.

My .02, Unless you are in love with that boat, I wouldn't spend the time or money trying to make that hull fast. Just enjoy it. If your mission is to go fast, find a more efficient hull.
