Well I have had my boat out on the water quite a few times now and have been having trouble getting it to plane out. At first I thought it was because of too much weight in the rear. That doesn't seem to be the issue now. I can fully use my trim all the way up and all the way down. The problem comes when I try to accelerate or pull the trim up while moving, it will go up a little then the pressure from the prop pushes it back down. If I try to lift the trim while idling the motor falls back down at about half throttle. Any ideas on this, I suspect a leak somewhere that is making me lose pressure, just don't enough about them to start looking for the leak. Any help would be greatly appreciated.
