Moving the new seals slightly off their current positions on the shaft
may fix the problem. Set the new seals with permatax 1 and use plastic
washers. Space between seals needs to be vented. Or replace the shaft.

I am having problems with this cooling pump.

This pump has been overhauled twice and apart from that it has been
serviced with new seals but it keeps developing a leak. Last time (2
months after overhaul) the seawater crept through 2 seals into the
engine block. I had to take out 2 gallons of salt water. Now it starts
again to drip. since that last servicing I have only been in clear
seawater.

I'm thinking of :
1) some mechanical ceramic seal that will do the job properly and for
years but I have no clue how to go about that one.
2) removing the waterhoses from this pump and add an electrical pump
with enough capacity and proper alarms and so on.

I would be obliged if you could spill your experience / thoughts
regarding this.
