[C320-list] Water Pump Repair or Replace Recommendations

[Jon Vez]

Dennis,

I did option #1 with the exact same symptoms two seasons ago. Took care of the problem. I closely watch the area to make sure there are no continuing problems. I've put about 80 hours on the engine since I fixed this problem with no problems since. I did it myself in about 20 minutes--very easy to do if you can turn a screwdriver. If you are going to have mechanic do it anyway and you *trust* him, you can always ask for his opinion...

Regards,

Subject: [C320-list] Water Pump Repair or Replace Recommendations

My boat has a leak in the sea water pump at the front seal (where the shaft comes out of the pump).  The pump does the job, but continuously throws off a little water from the shaft at this point. As I see it, I have three possibilities for repair: 1)  replace the seal, impeller, o ring, and gasket – parts maybe $35, 2) completely rebuilt the pump – parts kit $147, 3) replace the pump – $245.  I expect to have the yard to do the work, so labor will be at least $90/hr.

I know many of you have rebuilt your pumps and would appreciate your suggestions/recommendations.  If I go the route 1) replacing only necessary parts, have I missed any needed parts?  Also, with water coming out shaft end, it suggests that it is passing through the bearings and might indicate that they need to be replaced as well?   Finally, what would be your estimate of time required by an experienced mechanic to do the repair? The engine has less than 200 hrs. running time.

Thanks.
