I'm curious about what would be the optimum anti-cav plate height for my boat.
It's a 63" wide 14' aluminum with a 15" transom. I've got a short-shaft 25HP Evinrude on the back. On the motor, the distance from the top of the transom clamp to the cav plate is 17.5", putting the plate about 2.5" below the keel of the boat.
I've read that the cav plate should be even with the keel for least drag. Does that apply to this motor too? Would I gain anything by using a jack plate to bring the motor up?
Right now, the boat planes out nicely with one person, but if I'm carrying a buddy with it has a heckuva time getting up on step. It's still got the stock pitch 9x10" prop. WOT rpm is about 5200-5300.
