The manufacturer of your boat's engine(s) will provide a separate maintenance
schedule. See the Engine Operator's Manual for specific information on
maintenance procedures.

FUEL SYSTEM

A fuel tank vent is usually located in the filler deck plate or near the filler.
Periodically check that the fuel fill and vent lines are free of obstructions and kinks.
Check and/or replace the fuel filter periodically or clean as needed. Check fuel
lines, vent hoses and drain hoses frequently for leaks. Replace any worn or
cracked hoses.
Tightening a fitting or clamp may correct a fuel leak. If the leak continues,
however, replace the line, fitting or hose immediately to prevent a buildup of fluids
or gases.
Use fuel system parts certified for marine use only. Never use automotive parts in
marine applications.
