quick and to the point. Whats the difference between Ymalube lower unit oil and lets say Lower unit oil you might use for a Johnson/Evin seahorse 35 1981yr model?

I have had some say you cant use Yamalube in both a 2004 Merc and some say you can....KNow can tell me as I am just about ready to use thew Yamalube lower unit oil on that 35 seahorse.

If you can't then what product should you use and where is the best place to pick it up:) Thanks in advance...Henry

Hey, Henry. I think you will only find speculation on what brand of gear lube to use. On that `81 OMC. I would say use any SAE 80W-90 gear oil designed for outboard gear cases. That old motor was alive long before synthetic oil was developed, but you can use that also, I think keeping contaminates (water) out of the oil is more important than the brand of oil you use. Try Walmart for the best price. Pennzoil brand.

EIKNIB , Thanks for the straight forward answer to my question. The only reason I ask is because someone mentioned that i should not use yamalube type lower unit oil on a OMC engine and I grimced as to why anyone would make that statement....

And I agree that its about keeping the water out, then the brand...

But was looking for input from knowledgable others....

Sorry, Henry, it looked like your thread was sinking quickly to the bottom, with 0 replies, so I was just trying to keep it from dying. It appears that we don`t have any oil chemists on the board, who can give you the type of informative information you are looking for. I don`t think them ol` gears really care what brand of oil they are bathing in. Heck who ever changes the oil in the rear end of rear drive cars, similar application, similar oil, and some must have the same oil for 30-40 years. Of course a rear end is not prone to water immersion problems.

My friend is a marine mechanic and he has 2 types of foot lube...regular Quicksilver and High perf(synthetic) Quicksilver. He puts either in EVERY brand make year and model I/O and outboard he services. I run the Synthetic in my Suzukis and my OMC. Also ran it in my Yamaha when I had one. Regular lube is gold, synthetic is blue/green. Penzoil is fine as well, especialy their little install pump which works darn good. I just refill it with his synthetic when I do the foot.

Thanks Big:)

Seems it really dosn't matter what flavor you use as long as you make sure your not getting water in her, strip out the screw or do somethimg else weird.

I ran her yesterday she started on a first pull each time I started her:) very pleased with that 81 seahorse.

I don't know where I heard "don't use anything but Evinrude Lower unit oil on her" But it seems thats not true...

With the onset of old age, I don't remember the cut-off dates now, but I remember a time when with OMC engines it DID matter what you used.

One OMC grease was called HI-VIS and the other was called Premium. One had actual whale oil in it and was used for the electric-shift foot (like my Evinrude boat's stern-drive, and I think the original triple-cylinder loopers), and the other kind was used for everything else.

No real point here -- I'm just sayin' . . . [note the apotrophe AND the ellipsis]

I used to buy lubricants for a major international company and if I rcall correctly it was the early 70's when whale oil was prohibited. I do know our engineers considered it "the best" and they had a hard time testing, approving and specifying other oils for certain severe applications.

I knew whale oil is prohibited, but I didn`t realize it was the best. Whales might become alternative fuels. maybe we can farm them like salmon, in the Great Lakes. I gotta look into this. It might also improve the economy in Michigan. After all if we grow them for fuel, its no different that growing beef for food.

"whales per gallon"....? In this day and age that might actually come to pass.

If whale oil is used for 2 stroke oil, Does it smell like chicken?
