What i really meant was, changing to an external pump to save £50 wouldn't be practical as the external pump would cost much more than that. If yours is totally kaput, an external pump would be cheaper than £900 for a new one.Jeanneau Merry Fisher 805 For Sale. www.gooch.co.uk

If you are going to fit an electric pump it would be advisable to wire it through a relay which is switched from the oil Pressure switch so it only runs when the engine is running or you may accidentally fill your exhaust up with water!

As has already been said, the price for the impeller at about £30 is fairly typical. The two seals are about £10 each which is a bit steep. However, fitting a complete new pump will cost far more than £50 and involve the risk of further complications.
The original Albin pump is an unusual and clever design as it is actually two pumps on the same shaft. The front one handle the raw water. The rear one circulates the fresh water on a fresh water cooled engine. On a raw water cooled engine it acts as a motor-drive bilge pump and there is a small bleed hole between the two pumps to stop it from drying out.
If you engine is fresh water cooled then you cannot simply fit one new pump as you suggest. If it is raw water cooled, do you plan to buy a replacement bilge pump too?
I think that it would be unwise to modify the engine just to "save" £50.Dave Seager

Having read the origina thread and this one, it sounds like you may be lucky if the pump seal is the problem as it sounds like the volume is too high and getting through to the rocker cover through the valve lifters which implies that water may be flowing into the combustion chamber ........ but I would definetly try the simple things first as the tend to be somewhat cheaper than the big jobs....Regards, Alf
