I am restoring a Merc KE 4 . Went on this site to learn how others were removing water pump cover. (I destroyed my Mark 20H plate and had to replace it.).
As was looking in my tool drawers, I ran across this spanner wrench I’d found at a garage sale. It is made by Wright Tools (tool number 9636). I tried it and it worked. I had to tap the end of the tool with a peen hammer and used Kroil penetrant, but plate released fairly easily. Don’t think it has ever been removed previously. I’m adding a photo. Tool might be available at White Cap stores or ordered from them.
it’s adjustable and pins fit perfectly and just long enough. Mine is a 2” version.
hope this helps

I’m rebuilding a Mercury KE 4. Remembering what a pain it was to replace the impeller in my Merc 20H, I was not looking forward to the chore of replacing the KE 4’s water pump cover. So I went on line and found this site. Still no easy answer. BUI…I remembered I had found a tool I believed would work in a garage sale. I found it and tried it. Worked like a charm—even though I don’t believe the impeller had ever been replaced.
It’s called a Spanner wrench, made by Wright Forged Tools. And they still make these. Mine is a 2” model (tool “9636). I called the company and they said these can be ordered through White Cap tool stores (Nat’l chain). The 2” is smallest, and adjustable. They have a 3” and a 4” , but size of tangs are larger. My 2” fit this motor perfectly. With a few taps with a peen, it loosened.
Here are photos of mine.
Hope this tool works for others, too.
