So far nobody has rebuilt units. (I am open to suggestions on where to look). If I have no alterntives by tomorrow I'll order the repair kit from a store that has it for $87 and do the work myself. (Another skill to achieve... task to have performed... on the great checklist of... boat ownership)

Well, two different companies that list the repair kit "in stock" for under $100 did not in fact have one

- and couldn't get one for at least a week.

So I ordered one at a higher price + 2 day shipping, about $135.

So I know what I'll be doing this weekend.

The problem is that fine grit works it's way in between the shaft seals and the shaft. Not only does the seal leak but as the shaft spins the grit acts as an abrasive and a groove forms in the shaft. In most cases, new seals will not seal against these grooves. I'm guessing that this influences the number of rebuilt units available. I would strongly recommend removing the pump and seals and inspecting the shaft before you spend your $87.00

Ditto on inspecting before buying the kit. If the shaft is groved you could be wasting your money. Buy a new one and keep a rebuild on hand if you are cruising. If you have the dimenions you can find generic seals on line.

Ok, I got the kit, I have removed the impeller, undone the 4 bolts and the hoses - and the pump won't budge. I've tried tapping it with a rubber mallet, but because of where it is on the engine I can't get a clear knock on it from the back.

Suggestions on how to get this pump to let go of the engine?

PB Blaster and wait a day. Take a large screw driver and tap the joint with a hammer all around. Once you get frustrated, get a bigger hammer and indulge in self-therapy.

Well, PB Blaster and a few days waiting, a little wiggling the tiny separation with a thin blade, more PB Blaster, a whole bunch of raps with a ball peen hammer in the two places where I could get a 3-4 inch swing, more waiting, more wiggling the crack, more raps, and it's finally off. Dang gasket had turned into glue.

Now to try the rebuild and see if the directions make sense.

Btw, while waiting for the PBB to work I took off the reservoir, a couple pipes and hoses to add to my collection for cleaning at home. Lot's of slime in the coolant plumbing.
