I just bought a 1990 HS VS 150 T. It has a rude 150XP on it with a 6 inch manual jack plate. 24 raker prop. The previous owner had a whale tail on it. I took it out the way I picked it up and it came out of the hole like crazy. After trying to trim the motor up to lift the hull and get going all it wanted to do was porpoise real bad. I could trim the motor way down and plow the hull but that is not going to work long term. When I got home I measured the pad to prop shaft centerline and it was about 6.5 inches. Everything I have read says about 3.5 inches is w?here it should be. That is where I moved it to but haven't had a chance to test yet. Any advise on this particular hull/setup? What about the whale tale?????? leave it or take it off?
