I just bought a new Lowe Singer HP 18 w/ 115 optimax pro xs, went to pick it up today and the prop they had on there was a 22p and the boat was very hard to steer at 3000rpm. max rpm was about 5600 at 56 mph on the dash (not gps). I noticed at top speed and on plane the boat was easy to steer, but at lower speeds the boat was difficult to steer and felt very grippy or catchy. I left the boat there so they could order a new prop. ANY SUGGESTIONS??? Or better yet does anyone own one of these boats or know of anyone who does? THANKS
