My Johnson 175 started a slight knock at 4000 rpms but would go away at 4500 or 5000. No knock at low speeds. Engine still runs strong. Getting oil for sure and the water pump is still pumping. I think it's a valve knock. Sound right to anyone out there. Time for a re-build?????
I need to remove the outdrive and replace the U-joint bellow and bearing seal. I have been told that a manual was never produced for this year Yamaha. I have searched and cannot find one. Is there another manual that I could use that would be similar. 1993 Yamaha 5.0 YEMS:confused:
