It is easy to remove the pump.
1. Start by removing the rideplate. Bag bolts.
2. Start unbolting the pump from hull (4 bolts). Make sure to mark any shims there may be, and bag the bolts.
3. Slide pump straight out, like the pump fell off when ski is moving.
***Watch for any alignment pins that may be in the pump. (where it bolts)
4. Remove the 4 long bolts keeping pump and impeller/wear ring together. Bag bolts.
5. Pry pump and other parts using tabs and separate. Watch for alignment pins and bag.
Done.
No matter what I do, I always end up with too much or lost hardware.
