Re: Cure for porpoising flats boat?
Waterrazor<br /><br />I don't think there is a sure fire way to fix that problem.I screwed around with a 22' flats boat for 2 or 3 years with the same trouble.<br />What is the length and HP rating on your boat?<br />Mine was rated for 200,but I started with a 175 which porpused just like yours.At first I thought my prop was losing bite letting her fall off.Went with a deep cup prop,and it got worse,telling me she didn't have enough power to hold the bow up.<br />With the 175 the combination what worked best was a set of shims to reduce the angle of trim,and raising the motor up on a jackplate.Ran smooth and gained 4 mph.<br />Later on I put a 200 on her with a deep cupped prop,and took the shims back out.She then had the power to hold her up.Ran smooth and gained 15 mph.<br /><br />Hope this helps
