Hi all ive got a 26 foot Fiberglass that weighs around 3000kg with a single AD41B 200hp Volvo Penta Diesel running a 290 sp Leg with a 15.5x17 prop and im finding it very hard to get on the plane. at WOT its only reaching 3400 rpm and at 17 knots but sometimes it can reach 20 knots?? but very rarely it gets to that speed. Do you think thats the wrong prop size??
