More Time on the Water. Less Downtime for Maintenance:
Lower Total Cost of Ownership. It’s a commonly held belief that boats are high maintenance, yet. when your vessel is powered by a Cummins diesel, the truth is. just the opposite. A recent analysis of routine maintenance practices on Cummins powered vessels, along with a meticulous review of the impact on performance, reliability and durability of our engines, has resulted in substantial increases in the recommended intervals.
for required maintenance on our marine diesel engines in both commercial and recreational use. That includes all Cummins.QSB6.7, QSC8.3, QSL9 and QSM11 engines, regardless of model year. As you will see from the maintenance chart, virtually all of the normal maintenance items are now extended out to a year or more if the hourly limit is not reached.
Some procedures, such as the cooling system flush and vibration damper cleaning, need to be done only every four years or 2,000 hours. For most owners, that means that you simply do an annual checkup. The only exceptions to the list are the zinc anodes, which need to be. Replaced every six months or 250 hours of operation. Having less downtime for engine maintenance means a lower total cost of ownership and an increase in the amount of time you can spend. on the water.
Operating Hours Versus Time-Based Intervals.
As you use this chart, please note that even though many specific maintenance items should be performed at annual intervals, the number of operating hours can vary between 250 hours.
(Draining and refilling the lube oil and filter and checking drive belts) or 500 hours (most other service items). The required maintenance should be performed when either threshold is reached.
Some
items, such as the overhead set adjustment, are based solely on hours of use while others, such as inspection of the aftercooler assembly only on the QSB6.7, QSC8.3 and QSL9 are strictly on
a calendar basis. Aftercooler assembly has an hour interval of 1500 hours on the QSM11. Preventative Maintenance Schedule For Cummins Marine Engines.
