WARNING
Avoid fire or explosion hazard. Electrical, ignition, and fuel system components on Mercury Marine products comply with federal
and international standards to minimize risk of fire or explosion. Do not use replacement electrical or fuel system components
that do not comply with these standards. When servicing the electrical and fuel systems, properly install and tighten all
components.

WARNING
Neglect or improper maintenance, repairs, or inspections of the power package can result in product damage or serious injury
or death. Perform all procedures as described in this manual. If you are not familiar with proper maintenance or service
procedures, consign the work to an authorized Mercury Marine dealer.

WARNING
Performing service or maintenance without first disconnecting the battery can cause product damage, personal injury, or death
due to fire, explosion, electrical shock, or unexpected engine starting. Always disconnect the battery cables from the battery
before maintaining, servicing, installing, or removing engine or drive components.

Without sufficient cooling water, the engine, the water pump, and other components will overheat and suffer damage. Provide
a sufficient supply of water to the water inlets during operation.

Starter Specifications
The Permanent Magnet Gear Reduction starter motors features small permanent magnets mounted inside the field frame (NOTE:
The actual configuration of these magnets differs between the PG200, PG250 and PG260; the field frames with permanent
magnets are not interchangeable. Otherwise, the units are similar.) These magnets take the place of current‑carrying field coils
mounted on iron pole pieces. A 4:1 ratio Internal gear reduction results in armature speeds in the 7000 RPM range. The armature
and drive shaft are mounted on roller or ball bearings in the place of bushings. The solenoid switch, plunger, return spring, and
shift lever are permanently mounted in the drive housing.
