Thanks for the replies so far. As far as the prop, It is a un repaired un damaged 4 blade 13.50 x 16.00 (.105 cup).
At wide WOT I am cruising 42.5 (on GPS), at 4830rpm.
The boat is used mainy for course skiing, but I will weight the boat and throw 4 or 5 people in it and wakeboard on the weekends. 750lbs in the back and 300 in the ski locker + people.
So I would like the prop to be able to do both well, but I understand that there will have to be some compromises.
So for the guys with the slot it looks like yall are seeing close to 1:1 RPM to speed? (ie 36mph = 3600 rpm give or take)?
