Changed Outdrive oil added Prolong

Re: Changed Outdrive oil added Prolong

Bruce if doesn't hurt then it must be good. Question is how much good? That's like putting stabil in your gas and your engine fires right up. Could possibly mean that you have a greater ratio of good fuel than water. That suit was over 13 years ago. Thanks for the input.

Except for the fact that the Prolong is displacing the extra volume of oil needed to lubricate the drive.
I can still remember the silly Prolong infomercials of the late 90's with Al Unser driving a Viper around some desert test track, acting like this miracle product saved the car from the heat. Little did the people who bought that stuff know that Chrysler did the exact same thing before sending the car into production. They were competing with the likes of Duralube, Motor-up, Slick-50, and Z-Max. And it made for hilarious Sunday morning infomercial claims of who's product's the best.
But it's your money...

BTW, Stabil isn't meant to treat moisture in your fuel. It's a fuel STABILizer that helps fuel stay fresher over long periods.

True! Stabil doesn't have one drop of any type of alcohol needed to dry out fuel.

1. Not sure I trust a test done by someone advertising their own product.
2. Where do you see Mobil 1 mentioned at all?
3. What does this have anything to do with gear oil, the test is with motor oil?

As long as its GL-5 rated gear oil, its probably fine.
Gear oil - Wikipedia, the free encyclopedia

Bruce, I can't argue with point 1. although I have seen similar tests done independently such as on Boattest.com Re point 2, the silver bottle of oil is mobile 1. point 3 Royal Purple also makes GL-5 gear oil with the same additives as their motor oil. That's what I was asking about. Although you can't use their motor oil in engines with a Catalytic converter it works with everything else.

3 Royal Purple also makes GL-5 gear oil with the same additives as their motor oil.

Gl-5 is a rating...not an additive.

Sorry, tests like these are similar to Scamsoil and their studies.

I would like to see the tests that Boattest.com did. Please provide links.

I know GL-5 is a rating. Royal Purple makes a Gl-5 and GL-4 rated gear oil. Here are some the Boattest.com tests

Royal Purple Oil Test: After a Season of Use | BoatTEST.com

Double-Duty Lubricant and Anti-Corrosion Product | BoatTEST.com

Royal Purple Synthetic Oil : What Engine Oil Do Marine Professionals Use? | BoatTEST.com


Just FYI, I don't have anything to do with the oil. In fact I just bought 2 new Mercruiser 350 mags engines for my boat so I can't use the Royal Purple for the next 3 years without risking the warranty. I was just curious if anyone out there had used it and had any feedback on it.

Re: Changed Outdrive oil added Prolong

Although those posts are interesting, the fact that Boattest clearly points out that Royal Purple is a sponsor makes them a little suspect. I am sure RP is a good product as is Mobil 1. Probably can't go wrong with either.

With an OMC drive, and most drives, its not the gear oil used, as long as its the proper viscosity, but making sure the gear oil is at the proper level and there is no water intrusion.

Re: Changed Outdrive oil added Prolong

Thanks Lou, On the Allen Key plug. Ordered one to replace my old screw driver one. Should be alot easier to get to torque. Did not get up early enough today to get out on the water. Appreciate your input!

You should be able to get it lower than that, I can get mine to idle in gear in the water at 550 or so, out of gear its about 600, sometimes you have to do a careful tune up on these older boats including setting the idle mixture to get them to idle smooth and low.
And yes as the other posters said, you should not have the ESA engaging when shifting into gear, only when shifting out of gear, because it senses resistance on the transom shift cable caused by the dog clutch holding the gear you are in engaged. If you watch vids of how a dog clutch drive shifts you can see that. Watch this:

Lower unit training video, cut-away display OMC Cobra ShipShapeTn.Com - YouTube



BTW I do use the newer style drain plugs, with the allen key, they are sold by BRP dealers and they use the same nylon washers. I usually replace them every time and they don't leak. Make sure there is no dirt on the seating surface in the drive or on the plug itself....

What about Lucas Oil Stabilizer? Anyone messed with that?

If it doesn't hurt it must be good? (you won't know that until the drive self destructs will you?)

It always amazes me when anyone tries to justify this kind of "logic"

You're putting an unproven oil "additive" in a hypoid gearbox that REQUIRES GEAR LUBRICANT......... (not engine oil or transmission oil)
Hypoid Gear oil not only has totally different additives, but has totally different requirements.

Their own site mentions nothing adding to hypoid gear lube. and they mention auto or manual transmissions. (many manual transmissions use ATF for lubricant)

According to their MSDS, it consists of:

Hydrotreated Light Naphthenic Distillate
Severely Refined Mineral Oil
Naphthalene

And of course, the Snake-oil "Du-jour "........ "Proprietary Additives" (YEAH!!:facepalm


The only other "info" available are testimonials. There's no ASTM or SAE standard test data or info shown.

NO engine manufacturer recommends using that stuff and some will even void warranties if they can prove it was used and there's an oil related claim.

You might as well just run 40wt engine oil in your drive.

You're effectively diluting the high pressure additives in the gear lubricant.

But of course,

Oil and fuel additives make most people feel better. I like to just have a beer and call it good, but to each his own.

The good thing is you can replace your Cobra with an SEI drive when it grenades!

Mobil 1, Scamsoil Marine Lube, Royal purple syn, Volvo Penta syn, , Mercury HP, ETC syn, etc etc. Are JUST FINE.

Re: Changed Outdrive oil added Prolong

But oil stuff is always fun subject something works for 20 some years but spend more money on extra stuff unstead of change oil yearly. Hey if it is not my money go for it help somebody else make a good living it is the American dream. When I was young and dumb raced motocross and changed oil weekly no additives just oil worked great now that I am older and still dumb still only use the recomended oils and still working.

Ran today and did not call for a tow. But will start a carb. thread.

Don't really care what you do. Just posting the info so people don't follow your path.
