Mystery leak isolated

[Blow me down]

We have had hey mystery leak for some time while running the other day I opened engine has to notice water being sprayed from engine pulleys checked all hoses with no leak found this seems to be emanating from raw water pump seal when engine rpms are above 1500.
Has anyone ever it experience such a thing

Yes, it is actually quite common. I wrote up a thread this spring on rebuilding these pumps. It can be found here:

Great write up and photos just the info I was looking for.
thank you Dale for your effort and detailing the procedures.
Where did you find the parts?

Any of the usual Merc suppliers can source the kits for you - they are nothing special. The Merc part number is #8M0050018. You'll need one for each pump.
