WARNING
Electrical system components on gasoline engines and MerCruiser Sterndrives are
designed and manufactured to comply with U.S. Coast Guard Rules and Regula-
tions to minimize risks of fire or explosion.
Use of replacement electrical systems components, which do not comply to these
rules and regulations, could result in a fire or explosion hazard and should be avoi-
ded.
When servicing electrical systems, it is extremely important that all components
are properly installed and tightened. If not, any electrical component opening
would permit sparks to ignite fuel vapors from fuel system leaks, if they exist or de-
velop.
WARNING
Electrical system components on diesel engines are not external ignition pro-
tected. DO NOT STORE OR UTILIZE GASOLINE ON BOATS EQUIPPED WITH THESE
ENGINES, UNLESS PROVISIONS HAVE BEEN MADE TO EXCLUDE GASOLINE VA-
PORS FROM ENGINE COMPARTMENT (ref: 33 CFR). Failure to comply could result
in fire, explosion and/or severe personal injury.
