Re: Mercury Mark10 water pump removal

They make a puller tool. Stubborn ones need to be knocked out from top. Remove powerhead. I use all old ds, push it into top of wp cartridge, push off center to get ahold of bottom of wp cartridge and knock it out. Since you say you removed bearing I am assuming you removed threaded retainer cap, which you need a tool for. You may need to cleanup or replace bottom wear plate if it gets damaged.
