Globe Marine Run-Dry Model 815 Impeller for Oberdorfer 8514, B6593, Onan 132-0316 & Universal 295628

It is undersized and does not pump water. Commonly reported issue on other sailboat forums. Seller would not help other than to tell me to contact the manufacturer. Sorry, but it is your problem if you sell a part that does not work.

Works fantastic in my Oberdorfer pump on my M25 Universal diesel. Made in USA too!

Sounded like a great solution for my Universal M12 diesel with Oberdorfer pump, until it unexpectedly stopped pumping water - in rough seas as I started the diesel to head into my marina. Impeller appeared fine but apparently would not maintain prime. A moment of panic - I won’t order this product again.

Bought this impeller several years ago to keep as a spare. Installed it today to replace an older Oberdorfer 6583, but it didn't work. It didn't pull water through the pump. Reinstalled the old impeller and all was well. Now need to hunt for a different impeller. Universal M25XP engine.

put one on works great

DO NOT USE THIS PRODUCT! I’ve purchased an impeller sold by Globe Marine Products on Amazon on August 21, 2017 and installed In March 2018. The engine was commissioned in May 2018 at the beginning of summer sailing season. During summer sailing season I’ve experienced numerous problems with engine raw water pump self-priming after moving under sail with engine off. There was no water coming out of exhaust. Raw water pump is located bellow water line and no hoses, fittings or strainers are reaching above water line when the boat is leveled. In order to make raw water pump work, I had to loose pump cover plate to let air out, Sometimes it had to be done several times. I never had this kind of problem while using OEM impeller: 15 years of ownership with extensive cruising Between NY and Miami, Bermuda, Bahamas and Caribbean. Finally, while sailing South in October 2018, I was not able to prime the pump at all. A couple of miles offshore, I replaced Globe Marine impeller with used OEM impeller and everything worked fine! Has been sailing in various conditions for two weeks since and had no problems at all. If you examine attached pictures, you’ll see how badly Globe Marine impeller tips are worn Comparing to OEM impeller with over 3 times as much usage. Also, I observed that the engine was running hotter above 2100 RPM (Volvo Penta MD17D, Max RPM 3000) Not exactly overheating, but closer to red than before) I suspect that because Globe Marine impeller blades are softer, they don’t seal as well as OEM, Which can contribute to weaker raw water flow and, therefore, higher engine temperatures. If you still want to try this product, watch exhaust water obsessively and monitor engine temperature. Make sure that you have time, sea room and ability to purge the pump or replace impeller when you start the engine.

Garbage. Smaller feet means less suction. Didn't even last one season before showing cracks. Cheap plastic center showed wear on the slot and allowed shaft to spin inside of it.

Fit perfect and good for generators that need to prime themselves
