So even though we had a great ride today we ran into a trim tab issue when we came into the marina. My tabs would not go "up" no matter what I tried. I switched battery off a few times but still I would hear a bit of noise from the pump but very little to no movement. They worked last time we went out but seemed to stop today. The pump was making noise but no real action. Any ideas? its a 2001 classic with the 496ho. I don't have the large "k planes" I think they are called just the regular size trim tabs. If they are shot should I replace with something similar or go with bigger tabs?
