A highly respected memeber on another forum stand's right behind these and from what i see would be a very good replacement for OEM stuff so to speak. Any one have experience with this product.

Globe Run-Dry® Impellers

The Only Impellers in the World Guaranteed to Run-Dry for up to 15 Minutes

Time on the water is precious, so trust the most reliable components available. Tests prove that Globe’s Run-Dry® impellers outperform standard neoprene or rubber impellers and are guaranteed to run-dry for up to 15 minutes.

That looks like the hot ticket there as long as it didn't burn up the plastic housing instead. Maybe with a Hardin thingy like this http://www.hardin-marine.com/p-14544...rhaul-kit.aspx it would be ok?

looks good, I think I will order some.

no experience, but market speak usually turns me off, If you take that at face value, it may last 15 seconds to 15 minutes ie: gar, to last UP TO

Any idea what P/N you would use for a 1995 502MPI?

Impellers and housing are cheap. Even if you bought this one is make sure I had spares.

The basics, they're as integral to propeller selection as are peformance goals and boat type. Your specifications will help narrow the field.

Thanks I didn't see that section! Looks like Diamond Performance has them online $70 but a different p/n than the Globe site comes up with for this application fro Bravo.

FWIW years ago I remember I think Merc but not 100 % as someone in the industry did a volume water flow test against other aftermarket impellers. OEM Mercruiser Impellers flowed the most, Globe was below those numbers and some of the other aftermarkets impellers were worse at flow rates. I wish I had that info but do not anymore.

The but to this is everything has change as far as who is manu these as well compared to years ago. To bad there is not current testing numbers to see who has the best impeller flow rates for impellers.

I will say this for Volvo penta as Johnson makes their impellers and housings. it seems that a Jabsco impeller installed seems to flow more water and keeps the slightly engine cooler. FWIW.

Also impellers and housings are all about clearances and the correct tolerances to meet the volume / flow rates needed.
