Raw water pump ??
 
While doing spring maintenance, I replaced the raw water impeller. After I replaced and started the engine I noticed a small stream of water running from the small hole on the pump. I don't see any numbers anywhere. Anyone know where pump model number is?? Rebuild / replace??? Your input appreciated.

The one on the top of the shaft

More info on the engine itself, and a pic would go a long way.

That is a Sherwood raw water pump. Oberdorfer makes the other pump for that engine. You could rebuild it, (read about that here: http://www.sailnet.com/forums/diesel...rfer-pump.html) but do yourself a favor and don't...

Call Depco Pump in Tampa (or maybe St Pete) and just buy a new one. It should cost ~$200 The guys at Depco really are experts. Make sure that you get a catalog from them too.

[EDIT] Depco is in CLEARWATER, FL

Found a new Oberdorfer pump for about $275 plus shipping. Installation not to bad but lower mounting bolt pretty well corroded but I finally won the battle with it. Pump number is N202M-15.

Thanks to all for your help.

Now on to next issue.
