Ugly Impeller

[tg3690]

Put a new water pump kit on my motor last week. It has been about 3 1/2 years since I changed this one. It is by far the worst looking one I have ever seen come out of this engine. The book says to change it every year, some folks say it can go five years or so. I usually do it every 3 years. This one was about to self destruct. Glad I caught it in time.......

Factory impeller ?-----Or something else.----Sure looks like it was run dry a few times.

It's the one that came with the kit I bought from MasterTech......I believe it is a GLM kit, with new housing, bolts, gasket, and plate. Doing spark and compression tests is the only time it was cranked dry. Never started the engine dry.

I was working on the same thing on my 1986 85hp, 856x6l. The shaft had a grove right where the seal seats.......... made some steel shavings.........mix them with jb weld........ time will tell......... enjoy the pics...

The shaft looked good. I was just surprised how bad that impeller looked. Most of the time they almost look good enough to reuse. But if I go to the trouble of dropping the LU it's getting a new one.

That's nothing to worry about.
Some Mercury WP kits come with a rubber seal/boot that fits right at that spot.

Is every company making better parts ? And charging less money ?
Or are giant companies buying up everything they can ? Lowering quality and charging more ?
Free Enterprise. Sure is great.
