Oil

I've got a 1977 OMC Raven 190. I just put a trim pump on it . The service manual that I have says to use OMC Premium Blend Gearcase Lube but I haven't been able to find it. Is there a substitute that I can use instead that will work? I'm just getting it put back together and would hate to kill it already.
Thanks

I would suggest 75W90 synthetic gear lube, on syn blend. Mobil one makes a good one, or use the Merc one

Thanks I'll try to find some of that and give it a try.

Whatever you use in your upper unit will work in your trim pump.

As you likely know, the lower unit has to be type C.
