Yamalube Marine Grease FAQs

What kind of grease should I use on my outboard motor?

If it’s a Yamaha, stick with Yamalube marine grease. It’s engineered by Yamaha, specifically for their motors, and it’s what most manuals call for. Designed to hang on under high pressure, it holds up when things get hot or wet—exactly the kind of punishment a boat motor goes through.

Is Yamaha marine grease waterproof?

Absolutely. It’s one of the key things that makes it different from basic grease. This stuff is tested to resist water washout and won’t break down or mix into that pasty mess some greases turn into. It clings well and protects metal even when submerged or splashed regularly.

Who makes Yamalube grease?

Yamalube grease comes straight from Yamaha Motor Corporation. It’s the same grease you’ll find in Yamaha-certified service shops and is backed by ASTM marine-grade testing. If you're looking for peace of mind, this is what your tech would use.

Can I use other marine grease brands on my Yamaha?

You could—but there’s a chance it won’t meet Yamaha’s tolerances for load, RPMs, or corrosion resistance. And if something goes wrong because of it, it might even void part of your warranty. For a few bucks more, Yamalube is the safer bet.

How do you grease a Yamaha outboard motor?

You’ll need a grease gun and a bit of patience. Load it with a Yamalube cartridge, then find your Zerk fittings—those little metal nipples near the steering and tilt points. Wipe them clean, connect the grease gun, and pump slowly until you see clean grease coming out. Wipe away the excess and move on to the next.

Where do you apply grease on a boat motor?

Common grease points include the propeller shaft, tilt tube, swivel bracket, steering linkage, and steering cable. You’ll find Zerk fittings near most of these spots. Just remember: clean the fitting first, grease until it purges, then seal it with a thin coat to keep water out.

How often should you grease your Yamaha outboard?

At least once a year—more often if you're in saltwater. If you’re boating hard every weekend or trailering long distances, a mid-season touch-up wouldn’t hurt either.

How do I lubricate my Yamaha outboard grease points?

Your outboard's manual will point out all the key locations. But to keep it simple, look around the moving parts—steering areas, tilting arms, and any pivoting brackets. Clean off dirt, pump in grease, and wipe off old residue. You don’t need a shop to do it—just a grease gun, some time, and Yamalube.

Is marine grease the same as regular grease?

No, they’re pretty different. Marine grease is water-resistant and built to hold up where there’s salt, humidity, and a whole lot of moisture. Regular grease isn’t cut out for that and can wash off or break down fast on the water.

How often should I apply grease to a boat motor?

At least once per season, but check your manual—some parts might need more attention, especially if you’re racking up hours in rough or salty water. It’s easier to top off than to replace worn-out parts later.

At the end of the day, a few shots of grease can save you hundreds in repairs. YamahaOnlineParts.com carries everything from individual Yamalube tubes to value packs. Stock up, stay ahead of wear, and keep that outboard humming like it should.
