To determine whether a fuel flow problem is in your fuel system or your engine, follow this
simple method. Connect a six-gallon portable tank to the engine and operate the engine. If the
problem persists, the likely cause is with the engine itself. If the problem goes away, the source
must be in the boats’ fuel system. One component that should be inspected if a restriction occurs
is the anti-siphon valve. If fuel does not flow properly through this part, it must be cleaned and/or
replaced.
DO NOT
remove the anti-siphon valve and replace it with a regular barb.
Do not use fuels containing alcohol. Alcohol, particularly methanol, will absorb water. That
makes fuel more corrosive to metals in tanks and carburetors. It also shortens the durability of
elastomers such as hose and gaskets.
After fueling, inspect the fuel hoses, connections, and tanks for tightness, signs of leaks, and
deterioration. Annually conduct a more detailed inspection of fuel system components, especially
those hidden from routine inspection. Replace any fittings, deteriorated hoses, clamps or
connections immediately.

OMPARTMENT
The fuel tank compartments need to be rinsed periodically, especially when used in a salt-
water environment. Dirt accumulation attracts salt, creating salt crystals. Salt crystals can corrode
most metal surfaces if left untreated over a period of time. To help protect your fuel tank from rust
and corrosion, rinse the compartment with
FRESH
water. Remove the access plates from fuel
tank lids and inspect this area for leaks or unsecured lines.
The access plates on your fuel compartment lid seal this area. Over time the opening and
closing of these plates cause the o-rings to wear-out. Replace these o-rings as necessary to
maintain the watertight integrity of the plates.
