I have a small leak that seems to be coming from the water pump gasket which is behind the copper cover in the picture attached. Has anyone else dealt with this? Looking for any tips or advice on replacing the gasket—what to watch out for or any tricks that made the job easier.

That should be an easy repair, and it would be a good time to check the impeller.

I don’t have your engine, but these may help.

1) close the thru hull for the cooling water

2) remove the 4 screws and remove the cover

3) remove the impeller and inspect for wear, broken or cracked veins, etc. if you don’t know when it was last replaced, I would
replace it and write the date in a maintenance log. Putting some dish soap on the impeller can help get it back into the housing.

4) many of these pumps use a paper gasket on the cover. Others may have an o-ring.

5) if it is paper, clean the old one off, being careful not to scratch the housing surface. I like to put a little Superlube on the new gasket to help it stick in place. Inspect the cover plate for wear and make sure it is clean. Put it over the gasket and replace the screws.

6) if it has an o-ring ( I think usually on the cover), inspect for wear, nicks, etc. if it looks suspect, replace it. Again, I like a little Superlube on the oring.

if the pump is leaking from a weep hole, that is an indication of a bad seal that will require the pump be rebuilt or replaced.

:plus: Greg nailed the project.:biggrin:
It is an annual project @KGarvey . Learning to do it yourself will save you boat money for those really challenging tasks.

The leak could be from the seal behind the cover plate; beware that some model pumps use a paper gasket, some use an O ring. My pump leaked last year and a new lip seal solved the problem. It was simple to change without removing the pump; just remove impeller & grab seal. (See You Tube). Took 15 minutes. Replace with new impeller & cover seal and your problem should resolve. Try StayCoolPumps.com
reasonably priced parts. You can call them for your specific needs. Lip seal from Yanmar was $50 excluding shipping! Stay cool supplies impeller, seals, & bearings (if you should need them) kits for approximately $60.

I think it is the paper gasket that is leaking ( see attached picture). I'm going to replace it, although there are no tears in the old one so hopefully it has just worn out causing the small drip.
Thanks for the response
