1998 Yamaha 175 shifts and throttes up but won't move past idle
(little egg harbor nj. U.S)
I was running the boat around 3500rpm and it seemed like motor came out of gear. Engine stayed at rpm but boat slowed down. Pulled throttle back and shifted the engine into neutral, forward and reverse. Put it back in forward gear and tried to throttle it up, rps come up but will not move the boat past idle speed in gear. What could have happened? Something in the lower unit broke?
