Ok here is my situation, 1994 Harris flotebote 240 classic I/O 3.0L. 15 1/2 x15 prop. My pontoons stick out about 1 1/2 feet past the foot, creating a lot of dirty water/ turbulence causing blow out/ slipping. Installed a whale tail and it has helped out tremendously but it is still blowing out/ slipping. Next step (in my guessing) would to either be moving the toons forward to make them flush with the back deck or having them cut down to make them flush with the deck. Any thoughts or ideas to help eliminate/reduce the slipping/blow out I am experiencing?
