I'm relatively new to boating. I recently purchased a 1991 Javelin 373 F/S. The motor is a Johnson 150 outboard. I took it out the other day on the lake for the 1st time to see how she handles. Everything went fine except that the boat was jumping every small wave or ripple it hit. I felt like I was running in the gulf on a large cigarette boat. It was jumping that bad. I had the motor trimmed all the way in. Is there something else I can do to stop this from happening?
