Cummins 450hp Engine Overheats - Impeller Shaft Breaks

MUSTAD MARINE: Oct. 2009 - During a yacht delivery between San Francisco and San Diego one of the two Cummins Diesels overheats on a 50-footer. This video is about the process of tracking down this somewhat complex problem while off Pt. Conception. We continued the 120 miles to San Diego and made landfall without issue. The next day we received two new pumps from Tennessee.

@3Mudbone1 You forgot to put the "r" in your. You ruined your entire put down.

You keep returning to homosexuality when you are angry. Now you're adding incest. You have strange thoughts which are likely created from deep interest in the subjects. Pervert.

One of my co-workers forgot to open the seachest valve on a U.S.C.G. 41' aluminum boat with Cummins V-903M main propulsion engines and fried both Jabsco rubber impellers. He reenlisted and may have retired in the C.G. We had trouble picking up suction after that, probably because of pieces of rubber being in the passages. I went on to be an engineer in the best merchant marine unions in the world, then a west coast longshoreman refrigeration technician/ longshoreman.

Water pump failures are always a fun problem to have, around 200 degrees is nothing to worry about one of my diesels went to almost 300 and the hose going to the header tank exploded but the engine was fine (sucked up a plastic bag in the intake) One thing you should worry about though is all of those exposed hose clamp bands waiting to slice your arm open, you shoud get some Clamp-aid end guards on those.
