Is there a different brand sea water pump avalible to replace the plastic housing/fuel pump merc assembly on a 575SCI. I got "Tricked" into converting the plastic housing with the crap KPM aluminum housings and now they are worn out. And cannot get any responce from KPM. Every since I put the KPM replacements on I have had low pressure and higher temps.
Thanks

Boatfix.com has all the housings and kits.

Thanks for the imfo. But I am looking for an aftermarket replacement. To take the place of the merc sea water/fuel pump combination set up and still use the serpentine belt.

Hi, I sorry that you are not happy with the KPM products. Just to avoid confusion, are you looking for the KPM mercruiser water pump re-build kit?
If so and you have had problems, please could you send me a photo of the kit and the problems that you are having as we would like to sort these out. KPM products have undergone a huge product enhancement programme over the past year, mainly being centered around our new military and commercial customers. These improvements will also be filtering into the leisure market in due course.

Ok, a better pump is going to be a jabsco bronze housing, they make a direct merc replacement, but not for the combo fuel pump pos, so you will have to do some fab work there but don't think will be all that bad, they will out flow and out last the mercs, not sure about the ones you had...Rob

I have two KPM billet rebuild pumps with ~35 hours on them. They worked perfectly on my 500EFI's. I removed them about a month ago when I sold the boat and put stock pumps back on.
