Seawater Pump Pulley Removal/Install

After dropping in this past weekend, I noticed one of my seawater pumps is leaking a bit. I'm getting ready to do the replacement job for the first time. I've already bought the pump I need (this one), but I need to buy a 'power steering pulley removal/install tool set' in order to swap the pulley onto the new pump. I've seen conflicting information on what kind of set I need. Some sources say I need a metric set, and others saying I need one compatible with GM (and these appear to be SAE). Does anyone have any guidance or recommendations on which tool to buy?

    From the diagram, I think it's the same Lisle 39000 "no slip" pulley puller that I bought back in the day.  I still have it ... if you want it, I can ship it this week.

    I can tell you from experience -- regular 3-jaw pullers won't work.

    This looks perfect. Thanks but I'm going to order one from Amazon so I can have it tomorrow. Thanks!

    Pressing it back on will be the next challenge.

    That tool does removal and installation.  Easy peasy.  But it only works with that specific style of pulley.

    So I got the pulley off using Lisle tool no problem (with a little help from an impact gun). I was missing some other tools on the boat so I didn't get to wrap up the project yet, but I also am worried a bit about water ingress while swapping the pumps. I have thru-hulls for the water pump, but when I close the sea cocks I think water still comes in through the bravo drives. I tested this by opening my sea strainer, and even with the sea **** closed water just continued to flow into the bilge.

    When I disconnect the hose from the water pump, do I just shove a stopper into the hose? Is there a more graceful way to handle this? Also, isn't it a huge risk to have a water inlet that I can't shut off?
