I have a Sun Tracker pontoon boat with a 1999 Mercury 115hp ELPTO and power trim. I bought the boat used so have no dealer recourse. The problem is the motor cowling hits the back of the pontoon when its in the "trailering" position. The motor is mounted on the transom as it came from the factory but the trim allows it to come up maybe 1-1 1/2" too much. Is there a way to set the range so that the motor will stop before it hits the back of the boat?
