Fuel Filters
A boat-mounted water-separating fuel filter
assembly will help prevent water and other
contaminants from entering the engine fuel
system.
Use of a boat mounted water-separating fuel
filter is highly recommended on all boats.
Boat-mounted water-separating fuel filter assemblies must meet the required fuel flow and
filter specification. Refer to Boat-Mounted
Fuel Filters on page 59.
