Re: 1988 Four Winns- Greasing U-joint
For this job you're going to be removing and reinstalling the drive, removal is not hard but the drives are heavy so you may need 2 people unless you have a strong back. I built a stand to hold it, here are some pix.
Greasing the u-joints is easy, the main thing you want to check is that the bellows does not have water in it and the gimble turns easily with no roughness. Checking engine alignment with an alignment tool is a good idea too. Installing is little tricker, it can be hard to get the driveshaft in straight. The original bellows were a tight fit and made reinstallation difficult, the newer ones are a bit bigger and make it much easier.
You can see R&R instructons at

look in product support under OMC Cobra drives. They have the instructions from the original manual there.
