Re: Bad prop causing slow speed?
Looks like I'll just accept that 25-27 mph is the best I can get with what I've got.
Maybe, maybe not. Two questions: has it always had the same performance, and what is the position of the vent plate relative to the water surface when at WOT? Vent plate about an inch above the keel is a starting point that may or may not be optimum. Take a look at the plate when WOT, it should be very slightly above the surface, but still getting splashed. If it's there, try a 19" or 21", you're over-propped at 17". If it not there, put it there and see what your performance numbers are. Oh, there's a reason the maximum recommended is the maximum recommended. I'm sure it will go higher, but you won't know how high until it comes apart ... :facepalm:
