Book Excerpt: 1984-1999 Force Outboard 4-150 HP Repair Manual
This chapter contains removal, overhaul, installation and adjustment procedures for fuel pumps, carburetors, reed valves, fuel tanks and connecting lines used with all engines covered in this manual.
Tables 1-3 list general torque specifications, reed valve specifications and fuel pump pressure specifications. Table 4-7 list carburetor specifications. All tables are at the end of the chapter.
All outboard motors equipped with an integral fuel tank use a gravity flow fuel delivery system and require no fuel pump or primer bulb.
The diaphragm-type fuel pump used on models with a remote fuel tank is operated by crankcase pressure/vacuum pulsations.
Since this type of fuel pump cannot create sufficient suction to draw fuel from the tank during cranking, fuel is transferred to the carburetor(s) for starting by operating the primer bulb installed in the fuel hose.
The propeller is the final link between the boat's drive system and the water. A perfectly maintained engine and hull are useless if the propeller is the wrong type, is damaged or is deteriorated. Although propeller selection for a specific application is beyond the scope of this manual, the following provides the basic information needed to make an informed decision. The professional at a reputable marine dealership is the best source for a propeller recommendation.
HOW A PROPELLER WORKS
As the curved blades of a propeller rotate through the water, a high-pressure area forms on one side of the blade and a low-pressure area forms on the other side of the blade (Figure 12). The propeller moves toward the low-pressure area, carrying the boat with it.
