25 hp 1998 johnson water pump

How do you remove the gearcase on this engine? I need to replace the water pump impeller. Used to work on these in a previous life. Left it in about 1977.

Remove all visible nuts & the trim tab.
I always put the shifter in forward gear prior to removal of the lower unit.
This aids in aligning the drive shaft when re installing by allowing the drive shaft to turn when you turn the prop. (You can't turn the drive shaft if the lower unit is in neutral)
May God Bless You.
