I tried the process, on a completely removed transom plate, what a joke.

As for removing the outdrive, I agree it's not that hard.
a grease nipple wont do squat for hydraulic pressure. there is a special tool (about 85 canadian bones) to screw into that hole that you manually fill with grease that hasnt failed me yet and yes they are salt water boats.

start by removing the helmet, 2 hex bolts hold the pin in, pull them then remove the pin(the pin has jack bolt threads sometimes, 1/4nc). push the helmet outta the way, up. undo the bellows clamps and water hose clamp. remove the back drive cover and disconnect the cable, remove the brass end and jam nut from the cable. loosen the cable anchor where the cable enters the drive. block the drive skeg so its roughly vertical, remove the tilt ram pins. remove the tilt/pivot pin retainer bolts and hammer both tilt pins in towards the bellows (you have to steer the drive hard left or right) until the drive is free. rock the drive away from the boat

if you arent keeping the rams just bust em off. sometimes the sideways hammering action on the rams helps to free the ram pins.

its important to remember to remove the retainer bolts holding the ram pins in place.

before reinstalling the drive put the shaft bellows on the transom plate and the exhaust bellows goes on the drive. at least thats how ive found them the easiest.

buy a manual, preferrably a volvo one.
