New to me 2014 Mercury 60hp 4 stroke motor with 30 hrs total on an 18ft pontoon. I used motor all weekend with no problems. Today when I was taking it to the boat ramp I gave it full throttle and it seemed like the prop or something was slipping. It reved but speed slowed down.This happened three times. I backed off the throttle and took it easy to the ramp with no further problems. I got home and removed the prop and checked the hub. All seemed fine. Could this be some lower unit problem? If it were a lower unit problem would it also slip at slow speed? Or maybe some cavitation thing that might have worked itself out if I had stayed on the throttle. I am going to take it back out and try it. But, wanted opinions. Thanks.
