Page 28: Systems Details
NTAKE AND XHAUST YSTEM The Intake and Exhaust System of the RAIDER Model 55 Outboard Engine is comprised of two sets of components, the intake and the exhaust. The intake side of the system is designed to allow air to be drawn into the engine so that...
Page 29 Intake and Exhaust System Components Cowling A series of circular baffles are integrated into the upper- rear portion of the cowling. These baffles are designed to allow fresh air to pass into the cowling while preventing most water from entering. Does not prevent water from entering during submersion.
Page 30 Reed Valves Set of flexible metal flaps which act as one-way valves. The flaps are free to bend forwards into the intake, allowing air-fuel mixture to enter cylinder. As the compression stroke occurs, the pressure from inside the cylinder forces the reed valves back the other way, closing them and preventing exhaust gasses from traveling backwards through system.
Page 31 Exhaust Pipe Directs exhaust gas from the combustion chamber to the gearcase, where it exits the engine through either the exhaust ports or the propeller hub. Through-Hub Exhaust Allows exhaust to exit the engine through the propeller hub, allowing the propeller spin more easily at lower speeds.
Page 32: Fuel System
YSTEM The Fuel System of the RAIDER Model 55 Outboard Engine is designed to store fuel and to deliver that fuel to the engine’s combustion chamber where it is combined with air, compressed, and ignited in order to power the engine.
Page 33 Fuel Pump Force fuel through the fuel system. The pumps contain internal diaphragms that move in response to crankcase pressure. This changing pressure causes fuel to be drawn in and pumped out through a series of one-way valves, ensuring fuel is moved in the correct direction. Carburetors Responsible for introducing the fuel to incoming air.
Page 34: Electrical System

The Ignition System is responsible for providing the electrical spark which ignites the compressed air-fuel mixture in the combustion chamber. Electrical System Components Flywheel/Magneto...
Page 35 Exciter Coil Works similarly to the alternator coil, but part of the ignition system. Provides power to the CD unit. Trigger (Pulser Coil) Part of the ignition system, the trigger detects the position of the crankshaft and relays the information to the CD unit.
Page 36 Ignition Cable Responsible for conducting the voltage from the ignition coil to the spark plug with as little resistance as possible. Spark Plug Part of the ignition system, one spark plug per cylinder is threaded into the head of the engine. The stainless-steel spark plugs are responsible for igniting the air-fuel mixture using electricity supplied by the ignition system.
Page 37: Drive System
RIVE YSTEM The RAIDER Model 55 Outboard Engine Drive System is comprised of the set of components responsible for capturing the energy produced in the combustion chamber, and transferring that energy to the propeller to generate thrust. The Drive System can be divided into three main subsystems, the Crankcase, the Gearcase, and the Gear Shifter.
Page 38 Drive System Components Engine Block/Crankcase Cover Houses combustion chamber, pistons, crankshaft. The crankshaft assembly is held in place by the crankcase cover. Cylinder Head/Cylinder Head Cover Two-part cylinder head houses the spark plugs, thermostat, and decompression valves. Acts as the ‘top’ of the combustion chamber, containing the air-fuel mixture as it is compressed and ignited, and directing the energy of the resulting combustion towards the piston.
Page 39 Flywheel Connected to the crankshaft at the top of the engine, the flywheel stores some of the rotational energy from the crankshaft as inertia. This inertia allows the crankshaft to continue rotating as the piston reaches the bottom of the power stroke.

Page 44 Cooling System Components Water Intake The opening through which the water pump draws water into the gearcase. A screen across the opening prevents foreign matter such as grass, sticks, and small rocks from entering the system, as this could plug the cooling passages and destroy the engine through overheating.
Page 45 Thermostat Cap Removable cover which allows access to the thermostat for servicing. Bolts must be re-torqued after removal to prevent water from leaking. Thermostat Cap Gasket Ensures proper seal of thermostat cap. Must be replaced if thermostat cap is removed. Water Jacket Passageways inside the engine block and cylinder head through which cooling water flows.
Page 46 Tell-tale Small opening which emits a stream of water, indicating that the water pump is functioning correctly. If little or no water is being discharged from the check port, check whether the intake screen is clogged. This is not the primary exit for cooling water, as most of the water leaves the engine through the exhaust ports.
