I had several little cosmetic things done to my boat over the Christmas holidays and new years. While my boat guy was doing these touch ups and adding some led lights he also did all my motor maintenance work. So today is the first day I have had a chance to fish since the maintenance. Boat performed just fine and never noticed anything different but I did not run above 60. When I was heading in for the day I was cruising along at 60mph with very little trim. I decided I may run a little faster so I decided to bump the trim up a little. When I did it felt like I just lifted the gas pedal. No miss that I could tell in the motor at all. Did it again and the motor rpm gauge dropped 100-200 rpm instantly. It did this every time I would just bump the trim up. When I would hold the trim down after the initial drop it would regain the rpm and the motor would just keep gaining speed as the motor trim went up. It was definitely noticeable when that very instant it would drop RPM. Any thoughts?
