NOTE: Minor, transverse cracks (across the belt width) may be acceptable. Longitudinal cracks (in the direction of belt length)
that join transverse cracks are not acceptable.
Replacing
IMPORTANT: If reusing a belt, install it in the same direction of rotation as before.
The belt tensioner operates within the limits of movement provided by the cast stops when the belt length and geometry are
correct. If the tensioner contacts either of the cast stops during operation, check the mounting brackets and the belt length.
Loose brackets, bracket failure, accessory drive component movement, incorrect belt length, or belt failure can cause the
tensioner to contact the cast stops. See your authorized MerCruiser dealer for service if these conditions exist.
!
CAUTION
Rapid release of the belt tensioner, or allowing the tensioner to snap back quickly, could cause injury or product damage.
Relieve the spring tension slowly.
1. Use a breaker bar and appropriate socket to relieve the tensioner. Rotate the tensioner away from the belt until it stops.
2. Remove the belt from the idler pulley and slowly relieve the tension on the breaker bar.
a - Tensioner pulley
b - Socket and breaker bar
c - Water circulating pump pulley
d - Idler pulley
3. Remove the belt and route the replacement belt according to the belt routing diagram.
4. Carefully release the tensioner and ensure that the belt stays positioned properly.
5. Check the belt tension.
