When I apply throttle, boat rolls to left bad like it's going to corkscrew underwater. Has power tilt and you can avoid most of it by milking the trim as it accelerates, but it's scarry. Boat is a small 14 !/2' Bass Master fiberglass (like a pro craft) with a 48SPL Johnson and a whale tale on it. Even after planing and triming, boat still seems to favor the left side a litte - meaning that it rides a little lower to the left. Equipment is fairly well balanced, boat sits good at rest in water.
