[C320-list] Freshwater pump leak

[Jeff Hare]

Paul, 

He's referring to the engine water pump that pumps antifreeze coolant, not the raw water pump that brings in seawater to cool the exchanger and exhaust. 

Also, there are 3 different Yanmar engines. 
*  3GM30F - Japanese Mfg  (used till around year 2000 hulls ~400-700-ish)

*  3GM30F - European Mfg (post 2000-ish hull ~700)

* 3YM30? - newer yanmar engine currently in use on the MkII 

They all have different raw water pumps, so the FB kit you mentioned I believe works only on the Euro 3GM. 

More detailed info is on our website somewhere. :)

The Yanmar Johnson water pump -- I checked while at the boat.

The part NR on the box is 09-45587 Service kit F4B-8/-9.
Like I said, it has everything you need to rebuild the pump.

You may want to to check with www.johnson-pump.com

You should be able to order that from any marine parts supply.
The part guy at my marina orders it for me and I get it the next
day. 

Best of luck.

There is a service kit available to rebuild the Johnson pump.
I think the nr is F4B-8/9. I've used this to rebuild mine
and it replaces everything that may leak.

I'll be going to the boat later today and and I'll check the
nr.

My yanmar freshwater pump has developed a slow leak. Does anyone know where I 
can pick up a reconditioned one in the US? This motor has only done 250 hours, 
is 3 years old, and not covered by a warranty.
