"The shifter is a real pain in
"The shifter is a real pain in the back side. The button is broken on the inside and must be replaced. You take the shifter off, then the plastic cover, some where in the process a couple of ball bearings fall out from the throttle tension device. Oh this brings back bad memories. My dealer was nice enough to print a breakdown for me.
To change the water pump, remove 2 5/8 nuts on lower leg, 1 9/16 nut in front of trim tab, remove trim tab to find hidden nut. Drop the lower unit down in neutral, prop spins freely. Remove slinger ring, plastic water pump cover and old impeller. Install new impeller on key that falls out, lube with Vaseline, force plastic cover over new impeller while spinning drive shaft clockwise. Install slinger and install lower unit, verify neutral. If not in neutral move front splined shaft with vise grips to find neutral. Pay attention to the cam positioned on the front shift shaft, that locks the engine down when in neutral and reverse. Lube topof drive shaft lightly with grease."
