"On the rear wandering, a jet at speed may/should have a slightly "riding on grease" feel of not being very well hooked to the water. Kind of a "speed on the edge of control" thing."
Regarding this comment in another thread...I just got done re-doing my boat after it being off the water for about 5 years. It used to have that "riding on grease" feeling, but now I think it's riding a bit more wet. The main changes are that I have aluminum heads on the engine, and the new seat frames are made from 3/4" plywood instead of 1/2" plywood. Could these affect how it rides that much?
