Do you have any recommendations on where to buy a new raw water pump for 1991 mercruiser 502s?

get the run dry rebuilt kit from Trick and forget about another impeller ever

Do I have to change the impeller annually?

The guys at Adams and Durvin near the old Eastgate mall (in the east end)have done right by me on some Merc parts I needed. Tell Bill that Russ Carter sent you.

Russ do they usually stock the parts? Dean

What is this "RUN DRY" impeller by Trick? Is this a Globe impeller? Any feed back experience on it? How much is the "RUN DRY" kit? I will be doing my sea water pumps this spring also.

Just do a search here on the technical forum. There's a lot of information on the pumps fromthose who have installed them and run them.

Sometimes that information is more useful than what I can offer as the guy selling them.

It does not use a Globe impeller.

We have the rebuild kits on everything from face boats to a para-sail boat the put 1400 hours on the kit in one season. No failures! The impeller is guaranteed for a full year.
