Default What’s your favorite gear lube ?

I just broke in my new drive and am changing the gear lube in the outdrive. Should I go with quicksilver sae 90. Or what brand do you guys like more ? Is bass pro gear lube decent because the price is lowest anyone use this?

With the annual expenses of running a boat, any potential saving on LU oil is not something that troubles me - I’ve just gone with the manufacturer’s branded product - of course they don’t make it and it’s just another product with their own label - but it means you can be sure it’s to the manufacturer’s correct spec, so therefore I just take the easy way out. If I really want to save that amount of money, it’d drop my cruise rpm by 100 - or maybe 50 would do it!

Never put any thought into it. Pretty much use whatever is in stock and cheap. Back when I ran 2-strokes, I also used Walmart brand TCW-3 for years without any issues.

In most everything use Royal Purple.

But changed mine week or so ago and had to get NAPA GL5 because they were out of purple. It will not stay in there long.

Whrn it comes to drives or lower units best not to cheap out on the gear oil. That is the weakest and most stressed parts. Quicksilver is good.

If it’s a smaller or older engine, I use the Walmart 80W-90 gear oil. If under warranty, I use the manufacturer brand. I don’t want to give any excuse for not following the manual to the letter.

Lol I say this not to be cheap because I'm not. I will use the quicksilver 90 w. But I was looking for more of the opinions of if you thought the cheaper 10 dollar a quart vs the 30 is any difference in quality. I remember reading somewhere when it was said that oil is oil. And there was a study done.

And I'm not new to boating either lol. Had this boat 20 years just replaced the motor and outdrive this year to brand new. Always used the quicksilver.

the advice of using the manufacturer's brand while under warranty does hold some merit, in my opinion, only because it could give them reason to give you shit over any warranty issues. Even though they lawfully can't deny it as long as it meets spec (from my understanding), they'll try to make you believe that they can. Depends on how much that headache and that battle is worth to you.

My preferred gear lube is Mercury (or Quicksilver) SAE 90 High-Performance Gear Lube.

I like it because I can find it anywhere, and it is not expensive.
