It looks like the mph is tracking just below rpm/100 until you get to 4000rpm and it busts loose and mph exceeds rpm/100. Either that hull has lots of lift and the reduced wetted area at high speeds reduces drag so prop slip goes down, or you achieved lift off. ![]() ![]() Either way, the grouper grounds are much closer with that stroker providing the go. Glad the prop is working out so far. Once you've had a chance to break in the engine and run the boat with a load in it, you'll know if it's enough prop. Dave
