I have a 2015, 22ft, pontoon and between 600-1000 rpm while in neutral there is a vibration where the motor mounts to the pontoon frame. The engine is a Yamaha 90hp. If I simply, increase throttle to above 1000 rpm while in neutral sound lessens and eventually goes away. Boat runs fine while in gear and as long as RPM is >1000 rpm no issues. Anyone else had this problem and do you know what the fix is?
