Gents, once again I am looking for advice from the broad band of knowlage out there.
The water pump on my Yanmar 1GM10 has a very slight leak when the engine is running. From the forum, I know is a problem as other owners have reported that the sea water drips on the oil pipe and corrodes it.
I have replaced the "O" ring between the pump and the block, replaced the impeller, the gaskit and cleaned the outer cover. The leak, about 2 or 3 drips a minute, is coming from a machined hole in the pump casing, which I assume is there to allow water to escape.
In addition I have cleaned and painted the oil pipe below the water pump, split a length of fuel pipe and slipped it over the oil pipe to give some protection from the dripping water. I have left the split in the plastic pipe open to allow air to circulate in case of condensation and fixed each end with a cable tie.
A number of questions:
Can I stop the leak by servicing the water pump shaft and bearings, if so where can I get parts ie ss bearing, seals etc?
Is this leak normal, and should I live with it?
If I have to replace the pump where will I get the best buy?
Any of the usaual forum advice or quips apreciated
