Raw water pump

[Klausen]

Because of the leaking of my raw water pump (D2-40) every 2 Years I ordered a spare pump from professionalmarine.it (Ancor 701). They sent it in 3 days for the price of €184 incl. shipping. Maybe that helps someone. Yes, I can change the seals on my old one, but for a quick change it can be a good solution.

That's a very good price.  I replaced mine for around US$350 earlier this year, and that was the best price I could find.

You shouldn’t need to change your raw water pump every 2 years unless there is some underlying condition.
In 15 years I serviced mine only once!

Yes I know, it's just a spare for a quick change. Afterwards I will fix the original one with new seals!

It is the shaft seals that usually go on the raw water pump, not the shafts themselves.

If you have a leak of salt water from the hole behind the impeller you can replace it easily by pulling out the impeller and hooking out the old seal. This seal has a metal spiral ( spring) in it that in my case has corroded a few times.

If oil leaks out of this hole it is a bit more difficult to replace. Have a look at euromarineparts for an exploded diagram of the parts. It is self explanatory.

You really should only have to replace the shaft if it has been scoured.

I've had two shaft seals ( both the salt water seals) go in the last 10 years and I believe this is a regular thing to go wrong. I haven't heard of the whole shaft going or the whole water pump needing replacement yet.
