2 things.
Make sure you wipe the grease from the top of the shaft before putting it back in place and make sure you get the shifter piece in the hole when getting the lower unit raised up that last inch and into place. It can be tricky.
Do you have to drain the oil? And if so what’s the reasoning?
What torque for pump housing bolts
Is any gasket sealer used where you drop the lower unit or in-between any of it?
How's your black max running? I have a 1986 and replaced the water pump and thermostats and now it pisses well but gets hot when WOT. At idle it's dead center on the temp gauge but quickly climbs at full speed. Do I need to replace the poppet valve?
Watched other videos and it said to put the boat in gear when removing and reattaching and now the motor is stuck in gear and won’t go back to neutral. Did you do that on your install?
