Does this gear perhaps have a trolling valve? If so clutch slippage and associated wear may be normal. If it has a trolling valve an external oil filter is often installed, and overlooked when servicing.

No trolling valve. Interesting to note that while in neutral at idle, the port shaft would spin at (estimated) about 5 rpm while the stbd shaft was stopped. Engine surveyor said that was nothing to worry about.

Just more port transmission questions though in my mind...
