Ive got a 19 foot fiberglass sling shot ultra 810 bass boat with a 91 mariner magnum II 150 hp motor.....its currently propped with a ss laser II 24 pitch prop....having trouble getting the boat to plane out.....severe bow rise.......its not overloaded........two passengers (500 lbs) .... full gas tanks (26 gallons) and minimal gear..... Is this a prop pitch problem? If so what pitch should i be running.......top end speed is not important... three blade or four? (currrently three).

Any help? Thanks

Re: prop help?

Try another prop with less pitch if you have one, or try to borrow one. Probably something in the 19-20" range. That prop shouldn't be that far off if the motor is running OK. Is it vented?
