Hello everyone. i just got a 1988 18ft bayliner with a 1990 force 150 with a 25in shaft. and the first time we took it out within the first hour i blew three pistons. and my buddy has an 1987 force 125 with the 20 in shaft sitting in his shop. so my questions is can i just swap powerheads and be back on the lake. thanks for all your input. Nathan
