Book Excerpt: 1977-1989 Mariner Outboard Motor Repair Manual 1- and 2-Cylinder 2-60 HP 2-Stroke FUEL SYSTEM TROUBLESHOOTING EXCESSIVE FUEL CONSUMPTION Excessive fuel consumption can be the result of any one of three conditions, or a combination of all three. Inefficient engine operation.
Faulty condition of the hull, including excessive marine growth. Poor boating habits of the operator. If the fuel consumption suddenly increases over what could be considered normal, then the cause can probably be attributed to the engine or boat and not the operator. Marine growth on the full can have a very marked effect on boat performance. This is why sail boats always try to have a haul-out as close to race time as possible. While you are checking the bottom, take note of the propeller condition.
A bent blade or other damage will definitely cause poor boat performance. If the hull and propeller are in good shape, then check the fuel system for possible leaks. Check the line between the fuel pump and the carburetor while the engine is running and the line between the fuel tank and the pump when the engine is not running. A leak between the tank and the pump many times will not appear when the engine is operating, because the suction created by the pump drawing fuel will not allow the fuel to leak. Once the engine is turned off and the suction no longer exists, fuel may begin to leak. If a minor tune-up has been performed and the spark plugs, points, and timing are properly adjusted, then the problem most likely is in the carburetor and an overhaul is in order.
Check the needle valve and seat for leaking. Use extra care when making any adjustments affecting the fuel consumption, such as the float level or automatic choke.
