Drive Belts

If any drive belts or pulleys need replacement or drive belt tension needs adjustment, see your Authorized Mer-

Cruiser Dealer.

INSPECTION

WARNING

Make sure engine is shut off and ignition key is removed before inspecting belts or pulleys.

IMPORTANT: Observe the following drive belt and pulley guidelines:

• Do not use belt dressing.

• Replace a belt if worn, cracked, grease or oil soaked. Always check condition of remaining belts.

• When replacing a belt, the pulley alignment must be checked under tensioned condition (brackets securely

clamped). A misalignment that can be detected by visual inspection is detrimental to the belt performance.

• If a belt is disturbed for any reason, it must be correctly tensioned prior to operation.

• Replace pulleys if worn, or clean if still suitable for service.

TENSION

1 All drive belts must be periodically inspected for tension and condition.

Inspect the serpentine belt for the following:

• Power Steering Pump

• Alternator

• Circulating Pump

Inspect the V-belt for the following:

• Seawater Pump

• Vacuum Pump (If So Equipped)

2 Check belt tension by depressing upper strand of belt at midpoint between the pulleys on the longest span.

If there is more than1/2 inch (13 mm) deflection for the V-belt, or 3/16 inch (5 mm) deflection for the serpentine

belt, see your Authorized MerCruiser Dealer to have the tension adjusted.

REPLACEMENT

NOTE: During belt replacement, do not force belt(s) into pulley grooves by prying with a screwdriver, pry bar,

etc. This will damage belt side cords which will cause belt(s) to turn over in pulley grooves and result in complete

destruction of belt(s).

Alternator Belt

3 Loosen mounting bolt and tensioning bolt. Move alternator. Remove old belt and install new belt. Adjust belt

tension. When tension is correct, retighten all fasteners securely.

Seawater Pump Belt

4 Loosen mounting bolt and tensioning bolt. Move seawater pump. Remove old belt and install new belt. Adjust

belt tension. When tension is correct, retighten all fasteners securely.
