Drive Belts
Drive Belt
All drive belts must be periodically inspected for tension and condition. Turn the engine off and remove the ignition key before
inspecting for excessive wear, cracks, fraying, and glazed surfaces.
!
WARNING
Inspecting the belts with the engine running may cause serious injury or death. Turn off the engine and remove the ignition
key before inspecting the belts.
In the event that the drive belt requires replacement, it is recommended that the drive belt replacement be performed by a
Mercury Diesel–authorized repair facility.

Cause
Solution

Abrasion
Each side of the belt appears
shiny or glazed. Severe
condition: Fabric is exposed.
The belt is in contact with an object.
This can be caused by improper
belt tension or tensioner failure.
Replace the belt and
inspect its route for
contact with another
object. Verify that the belt
tensioner is functioning.

Pilling
Belt material is sheared off from
the ribs and builds up in the belt
grooves.
There are a number of causes
including lack of tension,
misalignment, worn pulleys, or a
combination of these factors.
When pilling leads to belt
noise or excess vibration,
the belt should be
replaced.
