Re: raw water pump leaks at shaft
Hi,
I have the 4.3L version of the same system (although it has a Volvo engine and a OMC drive) I had the same problem earlier this year, a few drips everyday. Don said that this was a sign of failure and there was no way to rebuild them.
I found a place on the web (Kobe's Marine in MD) that had a killer price on the pump replacement, about $150-200 if I remember correctly. There is a model number break in the NC year that is important to know to order the right part.
I called them on the phone and with a couple more digits outside of the NC, he was able to identify the proper pump. The unit was a Volvo part, dropshipped directly from Volvo. Prefect fit.
Later,
