•If your boat is equipped with two fuel tanks use the fuel select valve (see "Fuel Select
Valve" on page 3–3) to select the main or aux tank. Select the tank to be used first taking
into consideration the distribution of your load as fuel is consumed. Performance will be
influenced by weight distribution.
See warnings and check list in Section 6, page 37 of the Sportfish, Cruisers, and Yachts
Owner's Manual. Reference "Fuel Tank Compartment" on page 6–7 for more information on
cleaning the fuel storage area.

After fueling, inspect the fuel hoses, connections, and tanks for signs of leaks or deterioration.
Annually conduct a more detailed inspection of fuel system components, especially those hidden
from routine inspection. Replace deteriorated hoses, clamps, connections or fittings immediately.
If you are experiencing fuel flow problems, there is a simple method to determine if the
problem is in your fuel system or your engine. Connect a six-gallon portable tank to your engine.
If the problem persists, the likely cause is with the engine itself. If the problem goes away, the
source must be in the boat's 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 with a regular barb.
