I have a great running 89 Yamaha pro v 150. Never had a problem out of it until all of a sudden I was running and reached 5000 RPM and the boat "lugged" and dropped back down to 4000 RPM. The boat usually runs between 58-60 MPH, but now will only go 50 secondary to the loss of power at top end. I checked compression and each cylinder reads 105. Changed spark plugs, fuel filter and made sure gas was good. Took the boat back out and it has the same issue. Any suggestions?
