Serpentine Drive Belt (All Other Models)

Avoid possible serious injury. Make sure engine is shut off
and ignition key is removed before inspecting belt.
Belt must be periodically inspected for condition and tension.
NOTE: Belt deflection is to be measured on the belt at the location
that has the longest distance between two pulleys. Normally this
location is between the power steering pump and belt adjustment
idler pulley on models without closed cooling. This location is
between the power steering pump and alternator pulleys on models
with closed cooling.

Check the tension of the serpentine drive belt. If there is more than
1/4 in. deflection on the drive belt, see your Authorized MerCruiser
Dealer to have the tension of the drive belt adjusted.
If any drive belts need replacement or tension needs adjustment, see
your Authorized MerCruiser Dealer.
