Been doing it that way for 10-12yrs. My B1 with XR gears has 300hrs on it, behind 700hp. We'll see when I get the new motor in front of it, how long it lasts.

That's pretty impressive gear life!
So would the mix be 5oz of the Prolong per drive? Or per quart of gear lube?

Per drive.. a little less than 10% is what it comes out to.. I believe the longevity of my gears has to do with the born on date. I think they made them better in the old days..

Thats funny, years ago, I mean many, many, a friend raced outboards, this is before any additives and Mercury didnt even have High Performance gear oil. Gear cases were not made to surface and do what he did with them. His seemed to last longer than most. His secret forumula was STP in the gearcase with the gear oil. He swore by it.

Would anybody reccommend the red line over the amsoil the guy who bought my new boat from took it from a 502 to a 509racing crb motorpushing 550hp and that was he put in it ( redline) Then took it to a powerboat place in mn to get the carb jets replaced and changed it with merc because he thought it was power steering fluid. Anyway that is a whole diffrent story but is the redline going to be any better for my hi performance motor then the 75 100 amsoil I just bought but have not put in yet. It is pushing 550 hp. I just dont know if thicker is better because the amsoil i got seems alot thinner.
The boat is a 99 260 Powerquest legend, Thanks for any Info
