Hello , I heard different lubes to use for 1985 OMC Stringer Intermediate Housing Tilt Clutch Assy.
The manual says 30wt oil. I found 80/90 gear lube in mine, And some say pack the assy with marine grease.
What you you say.
Thanks paul

Thank you for your input. 30 wt makes sense.
All three oil and lubes were told to me from people,
Even the 30wt from a manual was told to me by a person.
I was not sure if the manual from the person was the right book for my boat.
I have the right manual on order, in transit.

I'm a inboard boat person, simple straight forward system.
A velvet drive,borg warner uses Dexron II
A Harley clutch pack uses 20-50 oil
A GM vehicle uses Dexron II, III, IV
So OMC uses 30wt.

30w was the most common lube back then I really dont think it matters. It is a simple worm drive system my old rotor tiller was packed with grease. I would put a marine grade gear-oil due to water intrusipn it maintains lube properties unlike engine oil.

I just received the OMC stringer Service Manual,
It clearly states OMC Premium 4 cycle motor oil,
OR OMC HI-VIS Gearcase Lube
