Replacing water pump seal

[rvdriver]

What’s the best way to remove and install a new water pump seal?

I am rebuilding the lower unit in my 58 Big Twin.

This one is really stuck in there.

Thanks, Steven

A seal puller, or hammer & punch or chisel, screw driver with block of wood for leverage,
drill a small hole, insert a wood screw, and “pry”. Some work some days, some
work no days, lol.
At least you have room to work. I’m wonder about this crankshaft seal removal, without
using the “proper” tool.

That gearcase seal is not the original. Is it leaking?

Richard White might be making the crankshaft seal tool. richardsoutboardtools.com

Richard’s website says he hasn’t gotten the 40 hp upper crankcase seal removal tool
into production yet. I wasn’t planning on working on a 40 hp, but it came with the boat
I wanted. I don’t plan on ever getting another one…. especially a manual start, therefore
I’m hesitant about spending $58 to remove one seal. I do have a 56 Evinrude 35 hp
awaiting revival, but it appears that takes a different seal removal tool.

Yep, a 40 seal is larger than a 35. Personally, I’d run the one that’s in there unless it proves to leak in the future. Time enough to deal with it then.

I’m guessing it’s the original 56 year old seal. I had the torch on the flywheel several times
trying to get it to pop off, but I didn’t see where anything melted, i.e., the old broken coils,
so perhaps the seal didn’t suffer heat damage.
I may leave well enough alone with the seal. Perhaps I’ll just put on
new ignition components so I can at least hear it run once.
The Gale’s “Evinrude” lower unit has been gone through with
new seals, bearings, etc., so that can be used on other projects
if wanted. I think we decided it was off a 25 hp…… looked the same
as my 25 hp RDE-17 anyway.

Put some oil on seal then turn the crank and see if it bubbles (leaks).

Good idea Dave. I remember watching Tubs video demonstrating this.

Did I miss something here? rvdriver started this thread asking about removing a water pump seal and I don’t see where anyone answered his question yet. I have destroyed these old seals with a hammer and screwdriver to get them out, with difficulty, and would also be interested in an easier way to remove them.
Thx,
Dave

I’m usually able to get them out with my seal puller with one or two sharp yanks. I had one that was really stuck where the puller just ripped up the metal edge of the seal and I then used a pair of linesman pliers to grab the torn metal and pull the seal.
