I think it is better to buy a remanufactured engine
over rebuilding one onboard. With a remanufactured engine
you know it was professionally rebuilt plus you get the warranty. You might even consider replacing the old diesel
with a new tier two diesel
. Tier two diesels are computer controlled which allows them to burn much cleaner plus they are a little more efficient. Some are even quieter.
1300 hours is pretty low if it was a well maintained diesel. A well built diesel that has been well maintained can last as much as 10,000 hours. The key word though is "well maintained".
For a diesel what this means is frequent oil
changes...every 250 to 300 hours or once a year, whichever comes first. You will also need super clean, moisture free fuel
. A good primary filtration system can do this such as what Racor
The other factor in how long a diesel lasts is how it is operated. Probably the worst thing you can do is run a diesel under large loads at low RPM's or no load at low RPM's. Some people think this is the economical way to run a Diesel...nonsense! A low RPM
high load situation occurs when your diesel is over propped which means the propeller
has too much pitch
. Don't run your diesel around at 800 or so RPM
all the time...rev it up! Burn out the carbon. Diesels love to be run at higher RPM's. If your diesel cannot reach its governed maximum speed then you are slowly killing it.
