Anyone else have a 17' Nitro with a V-6 150 HP Merc? What pitch prop are you running, and what is your top speed? Mine (used) came with a 20", but the guy had it set up for water skiing and even at that it's too low. I know it will exceed 5500, but I don't want to find out how much it will exceed 5500 by... Guy at the ramp last week had a 26 or 28 and that seems like a huge difference. Suggestions?
