[C320-list] Water pump

[argates2nd at comcast.net]

Michael, 

I noticed no leak before the skreeching, which occurred after a 6 month layup and 5 hours of engine use.  When I first heard the noise I thought it was the alternator belt slipping. 

I found a new pump via web search and it was shipped from PA or thereabouts.  There is a plate that butts one side of the gasket that should also be replaced since the old gasket is likely to make a mess of that plate.  I replaced the gasket and thermostat at the same time. 

It is also a good time to replace the belt. 

It took me a while to see all of these needs which resulted in 2 shipments -- the 2nd shipment was an overnight because I needed it done before racing within a couple days.  

If I had had all the parts at hand the first time, it might just have taken several hours for the replacement -- and I usually learn how to do these projects the hard way -- taking at least 2-3 times what it would take a pro. 



One other time, I had a screw at the bottom of the impellar housing come out causing a big spraying leak behind the engine cover and onto the galley sole.  Reinserted screw. 



Another time, I had to replace a seal in the water pump.  It was a straightforward job.  That was a few years ago but I think leaking was involved. 



Although our boat is a Perkins 1995 #181, it only has 550 hours on the engine.  I think the water pump issues are from usage intervals from 6-7 month layups.  



I agree with Jeff's view below.  One beauty of the Bahamas is that if you want or need to sail and the wind stops you can anchor just about everywhere in fairly shallow water and out of traffic lanes -- to wait for the wind, etc.  Good luck, Rollie

Mike, 

Have you noticed any increase in operating water temp?  If not, and the leak is very light, you'll probably be fine for the trip home especially if you can sail much of it.   

If you're likely to be in risky weather or need to motor the whole way then the safe thing to do is replace it before leaving. 

They say its better in the Bahamas.  Better for people $ELLING $tuff than people buying stuff.  :)

RollieDid you notice a leak before the bearings seized. Or did it just stop.ThanksMichael 
PS I am sure it is the pump weep hole thats the problem all bolts and clamps are tight.

Michael, 

I replace the water pump in Perkins driven #182 last year.  The bearings went and it made an unholy screetch. 

It is close to a one day job to replace for a novice like me. 

I would not set off on your voyage without a spare in hand.  Rollie

Michael, 

You don't say that you have even tried to do anything to it. Is everything tight??? 

Sorry, I don't know anything about the Perkins. But the first thing I would do is 
tighten all the connections and screws in the cover of the pump.

Has anyone replaced their fresh water pump on an old Perkins. I am in the Bahamas and have noticed a very small amount of coolant drip on the bottom of the water pump. I am wondering how long it may last or should it be replaced the pump before I make the 200 mile trip home. Of course if I were in the states there would be no question but getting it here will be a challenge. Any ideasMichael  Ferguson169 Nauti Clew
