"You can do what you want but
"You can do what you want but I have never grease a gimbla bearing with any engine rinning.
You should remove the outdrive to service/grease the ujoints. They are as important as the gimbal bearing. With the outdrive OFF, you now stick your fingers in and spin the gimbal bearing to feel if it is nice and smooth. After doing this then grease the bearing and the fitting is as said ~ 4 oclock on the right side as you are facing the transom. You can watch the grease come out of the bearing and determine if it is correctly installed by where the grease comes out.
That is the best and ONLY way to do it in my opinion."
