Accessory Drive Belts
The alternator drive belt and supercharger drive belts are located under the
flywheel cover. The alternator and supercharger drive belt inspection must be
completed by an authorized Mercury dealer at the recommended interval. Refer
to Inspection and Maintenance Schedule.
Trim Thrust Guide Wear Pad
The 500R outboard utilizes thrust guide plates on either side of the driveshaft
housing to improve stability of the engine. As the engine is trimmed up or
down, the thrust guide plates will rub against the trim thrust guide wear pads
that are mounted on either side of the trim manifold. Check the clearance
between the trim thrust guide wear pad and the lower cradle on each side to
determine if replacement is necessary. Failure to replace the trim thrust guide
wear pad may cause damage to the swivel bracket. Damage to the swivel
bracket caused by the trim thrust guide wear pad mounting hardware is not
covered under warranty. Refer to the Inspection and Maintenance Schedule
for the proper maintenance interval.
