Don't forget to sand it down to fiberglass where it will bond.

What?!? Why on earth would you do that? Just scuff the bonding area with 36 grit for good adhesion.

This is how I did mine....
1. Without using the pump shoe, install the pump ensuring the drive shaft is in the proper location inside the hull. If you need help with this, here is a video... Build-a-BOB: Pump Install:
2. Remember your shim settings and remove the pump.
3. Sand the area where the pump shoe touches the hull.
4. Remove the pump seal from the wear ring.
5. Make a 1/8" spacer (this will replace the pump seal when you glue in your shoe). To do this, I cut a piece of 1/8" thick lexan (plywood would do) slightly larger than the pump itself and drilled a hole in the centre of it for the drive shaft to fit through. This spacer will be thinner than the amount your pump seal sticks out past the wear ring.
6. Place spacer against the wear ring by putting the drive shaft through the hole you drilled (remember to remove the pump seal)
7. Apply glue to hull and pump shoe and place the pump shoe in rough position.
8. Install the pump using the shim settings you used before, again ensuring the drive shaft is properly centered.
9. The spacer now should be between the pump and the pump shoe. Press the pump shoe up against the spacer and pump. Ensure there are no gaps between the pump, spacer and pump shoe.
10. Allow the glue to dry.
11. Once dry, remove pump and spacer.
**Note**
Depending on the curing time of the glue used, step 7-10 may have to be done quickly. Using a glue that has a longer setup time would be advantageous.
Once you have reinstalled the pump seal, you'll have to press the pump fairly hard against the shoe in order to get your bolts in. This will help avoid cavitation.
I used Plexus Ma320 to glue in my shoe and when it was dry, I used it to seal all the way around the pump shoe to the hull. This also filled any gaps and made the transition from hull to shoe seamless.
Unfortunately, I didn't take any pictures when I was doing mine or I would post them (a picture is worth a thousand words). In any case, I hope this helps.

Cf alignment tool is sweet makes it effortless as long as pump shoe is square.
