I had two imstances when the rpm started to increase on the port egine first time I had a folllowing sea in the hudson river. Maybe it cavitated. I took out thr nrxt a brought the rpm to 3000 no problem. second time was when i was making a sharp starboard turn. checked the trim and the outdrive is all the way down. any suggestions?? plan to take a trip toke lis this weekend thanks
