Belt Maintenance
•
Do not allow oil to contact the belt, oil attacks the construction of the belt, reduces
the drive efficiency and will ultimately cause it to fail prematurely.
•
Replace the belt if it cracks, splits, or as the adjustment nears the limit of its travel.
•
Note: Some boat builders may remove one or more of the alternators during the
installation of the engine. It is essential that when the alternators are refitted that the
alignment is perfect or premature belt wear will occur.
