Mercury Outboard Grease Fittings
Hate to ask such a numb question but can you grease Mercury grease fittings with a normal pump grease gun? Just doing a 100 hour grease job and the head wont stay on the fitting and when I adjust the threads on the gun fitting lose enough to go over the fitting it leaks when I pump it. Same issue on all motor fittings, tilt pin, swivel and pully. I use the same grease gun om my John Deere tractor and it works fine.

Just ordered a LockNLube head for the grease gun to see if that will help. Another interesting observation is several of the fittings are a press fit and some are screw in...
