Fuel Tank Cleaning And Flushing

IMPORTANT: Diesel fuel should not be left in tank during winter storage, as an
accumulation of rust, sludge, and wax residue will form.
Refer to boat manufacturer's instructions and clean fuel tank at specified intervals. Unless
specified otherwise, flush and clean diesel fuel tank every 1000 hours or 5 years, whichever
occurs first.

Drive Belts

All drive belts must be periodically inspected for tension and condition (excessive wear,
cracks, fraying, or glazed surfaces).
If any drive belts need replacement or tension needs adjustment, contact your authorized
Cummins MerCruiser Diesel dealer / distributor.
Avoid possible serious injury. Make sure the engine is shut off and the ignition key
is removed before inspecting the belts.
