Transmission whine's in neutral and at low trolling RPM's. noise disappears once moving at higher speed.At around 4000 RPM's I can here and feel vibration and when I pull the throttle back to lower RPM quickly theirs a definite Rumbling grinding type noise from the transmission. The motor is mounted perfectly straight .The shaft and the prop is not damaged.
The motor was previously out of align enough to shake the pss shaft seal and break the graphite on the shaft seal.We realigned everything but the noise is very noticeable. Does anyone have any suggestions? Unfortunately the closest dealer is 1000 miles away.
