    How do you prep Honda B100 9.9 hp water pump oil seal and mating surface before installing?

    No go on tapping it out and I did not want to hit harder. 40 years its been on there. Ended up making a cut with the dremel and yanking it out with pliers. For all the trouble this water seal was, I hope that I just did not need a new 0 ring.
