496 HO water pump

[3queens]

has anyone used the product that is being sold as a repair kit for these
comes with spacer plates and how to do it.they claim easy to do
:idea: sounds good but grinding off a part of water pump has me nervous

Don't!!!!!!!!!!!!!!!!!!!!!!!!!!
Just spend the money and fix it with Merc parts.
How do I know? I had a kit done and it lasted about 3 months. The repair place had put JB weld in it to smooth the grooves. Lesson Learned..... Do it right the first time.

why hasn't enyone come up with a fix for these water pumps. it's crazy the wear on these with only 20hrs on it when i did the first pump. i know i will be buying a whole unit this year by the looks of it at the begining of this season. if i recall right there was a artical about a co. in one of my boating subz

I went 2 years before needing it fixed. During my second service the shop suggested the kit. Needless to say they aren't working on our boats now.

I have apx 50 hrs on my engine (496) .
When is it necessary to do a repair.?

Every other year or 100 hours is quite safe - unless you stick the outdrive in sand often.

I have the impeller changed annually, regardless of hours. Usually,not always the tech can tell if you need a pump by the impellers condition.

Very true. Havasu tends to be a little worse if you beach a lot. I know people that have gone thru 2 impellers and a pump in 1 season.

While we're on this subject MAKE SURE your tech pulls the drive. Here's what Throttles Cobra's bellows"sp?" looked like.

I have thought of that
my pump after 20 hrs had grooves in the housing like the one in pics above after seeing that I will change the impeller every year. small price for big hassel on the water

that is what we found when i shattered a gimbal bearing. The bearing was shattered due to some rust beginning from a leaking bellows. :idea:

Scott, I know how you are about your boat... dont do it. Use stock, just replace the whole thing. I am due for replacement soon as well. I generally replace my impeller every year at the beginning of spring, last year I skipped doing it. I plan on just replacing the water pump with a new one. Its a bitch to get to it with the newer HO's, but after you take the rear seat out of your boat it will make things a bit easier to reach...
