5,100 hrs Came out of a 80ft yacht that sits up in the spring and used for fishing tournaments the rest of the time. 2-3yrs ago Injector burned a hole in the piston, so they had the pistons and sleeves replaced. They are selling, because the engines are no longer under warranty. They are replacing with new, so they have the warranty. They are at CAT now getting re assembled. We had to remove turbos and what not to get out of boat. Motors have been under warranty since new until August this year. Many new components. One has a recent rebuild. We have all service records and par test before we pulled them. One has a recent rebuild. Service records available.
