I have a noise at dead slow after transmission is warmed up, does not happen when pulling out of slip. Checked props, Watched shaft (not fun position underway, use ear plugs), checked alinement, changed trans filter and trans fluid. Had mechanic on boat just before haul out. ZF trans, starboard side only. Was told that is normal sound. Noise is a soft knocking on my boat. Not sure if he was right on not. 50 RPM up and it goes away.
