Which is the right grease? -one step beyond Bond-o's "any grease is better than none"

I have an Alpha one (first generation) with Mercruiser 3.0L 140 HP on my boat. I'm doing my first full-on "pull the drive inspect everything" service on it. So far I've pulled the drive, checked alignment, replaced the whole water pump, checked all the bellows, changed the drive gear oil. I'm now getting ready to reassemble the whole works. I remember reading somewhere that one of the maintenance items when you have the drive off is to grease the u-joints. When I was planning this maintenance last fall, I went ahead and purchased all the greases, oils, etc that I was going to need. One of the things I purchased was "Mercury Marine U-joint and Giimbal bearing Lube". Right after I installed the water pump and re-assembled the gearcase, I loaded up the u-joint and gimbal bearing lube in my grease gun, popped it on the u-joint bearing zerks and pumped until I saw the goo squeezing out. Figured I was good to go.
Today I was looking through the mercruiser manual for something else, and I see where this maintenance is covered, with the warning in bold: "Use only 2-4-C Marine Lubricant for lubricating U-joint bearings. The use of any other lubricant will decrease the life of the bearings." Did I use the wrong stuff? I have a tube of 2-4-C that I also purchased ( On my list I have it for other applications). Should I just leave be or re-fill the U-joint bearings with 2-4-C? Why the heck would Mercury have a product labeled U-Joint Bearing Lube but indicate that you should use something else? Am I just over-thinking this?

Everyone is going to have their own thoughts on this one. Its kinda like what oil do I use type thing. I would be inclined to leave it alone. If its going to drive you crazy and following the manual will make you feel better than do that. Its really up to you. I don't think anyone has ever had a u-joint fail because of the wrong grease.

And grease debate will ensue in 5,4,3,2,1........

Ayuh,... I'm guessin' that's a mis-print,... 2-4-C shouldn't be used with bearin's, roller, needle, nor ball bearin's,...

It's claimed that it's Soooo slippery, the rollers, needles, or balls will slide, rather than turn,...

2-4-C is perfect for bushin' type bearin's though,...

I use plain ole Chassis Grease for all the points you've mentioned,...

I think a bulletin superceeded the manual and the "right " grease is u joint and gimbal bearing lube.92-802870a1.I would leave it,had already done mine with 2-4-c when I researched it and I am leaving it.

If memory serves me correctly mercury marine U-joint and gimbal bearing grease was not available when the older service manuals were published. You're better off to continue to using mercury marine U-joint and gimbal bearing grease.

Gone into my tech collection as well. I used marine grease from the local NAPA store in my MC-1 (165 Inline L6) . Next time I pull the drive, I'll have the real stuff on hand.
