2-4-C Marine Lubricant or Substitute

[Boating_Al]

Can marine wheel bearing grease be use instead of 2-4-C to grease gimbal bearing on a Bravo II? This is what a friend of mine tells me he uses.

Some may disagree, I'm sure there will be debate. Been using marine tube (wheel bearing) grease in the gimble/ujoints/steering for the 19 years I've had i/o's and never had a failure. Keeping water out is critical. Don't have my manuals here, but there is a rating in the manual. As long as what your using meets the requirement you should be fine. pennzoil marine grease is in my gun.

Thanks for the info...

Here is a service bulletin from Mercruiser about using the 2-4-C on gimbal bearings and ujoints. What they don't say is WHY it was a problem. But they do tell the dealers. Seems the teflon in the 2-4-C causes the bearings to slide, instead of roll. Which is not good.

Bearings, particularly wheel bearings and the like, tend to heat up. Bearing grease is formulated to not liquify under normal bearing warming, and therefore stay in place rather than drain out. Additionally as Don mentions, certain additives and lubricating qualities yield results that are different than intended.

In critical components where high speed, temperature and friction are at extremes, minimizing wear is very important and recommended lubrications tend to perform best. Others may very well do the job reasonably well...but for a few more dollars why not best protect that expensive equipment.
