i have a 20ft.lt with a 200 it has great power with a boatload.i would go with pitch pocket and get the 150.you need a lot of hp. with a pump.you will be a lot happier.plus you won't have to run full throttle all the time.my boat gets better fuel mileage than my other 16ft.with a 90/65 because i am not running wide open to get places.good luck with your new boat you will be happy you bought it at 3 rivers marine.scott
