MerCruiser gasoline power packages are designed and manufactured to comply with U S Coast Guard rules and regulations to minimize risks of fire or explo sion Use of replacement electrical ignition or fuel system components which do not comply to these rules and regulations could result in a fire or explosion hazard and should be avoided When servicing the electrical ignition and fuel systems it is extremely important that all components are properly installed and tightened If not any electrical or ignition component would permit sparks to ignite fuel vapors from fuel system leaks if they existed Marine engines are expected to operate at or near full throttle for most of their life They are also expected to oper ate in both fresh and saltwater environments These conditions require numerous special parts Care should be exercised when replacing marine engine parts as specifications are quite different from those of the standard auto motive engine For example one of the most important and probably the least suspected special replacement part is the cylinder head gasket Since saltwater is highly corrosive the steel type automotive head gasket cannot be used A marine engine head gasket uses special materials to resist corrosive action Since marine engines must be capable of running at or near maximum RPM much of the time special valve springs valve lifters pistons bearings camshafts and other heavy duty moving parts are requ
