Portable fuel tanks for outboard motors are fitted with a manual priming bulb. It is squeezed a few times to draw fuel when
first starting the engine or to continue to provide fuel to the engine in case of fuel pump failure. Care must be taken to ensure
that the bulb is not over squeezed as this may cause leaks in the fuel system or flood the engine with too much fuel, making it
difficult to start. The bulb should be squeezed only until it becomes firm.
The tank is also fitted with a breather screw, which must be loosened to vent the tank when operating the engine. Ensure the
breather screw is fully closed when transporting the tank to prevent spillage.
Internal Lubrication System
The gasoline engines are lubricated by oil circulation from the sump (crankcase). Insufficient oil will cause the engine to
overheat and eventually seize. Excessive oil will foul the spark plugs, cause smoky exhaust and heavy carbon deposits. Both
will cause engine failure. Please add 100ml oil.
Mounting An Outboard Motor
The method of securing an outboard motor to the vessel use of hand-tightened screw thread clamps. These clamp the
transom of the vessel between the engine mounting bracket and the screw thread plates. Their tightness should be checked
each time the engine is used. A safety rope or chain should also be used to secure the motor to the vessel and prevent the
motor from dropping from the boat if the clamps get loose during vessel operation. On larger outboard motors, the mounting
bracket is usually bolted through the transom plate. This is a more secure method, but regular checks must be made for
looseness.
Trim Angle
By changing the outboard motor’s drive angle, the vessel’s bow can be made to rise or fall. The performance and stability of
a vessel depends a great deal on correctly trimming the outboard. The correct trim angle depends on the vessel’s handling
characteristics, the size of the outboard, the sea and loading conditions. Care must therefore be taken to ensure the outboard
is trimmed correctly under different sea and loading conditions. On smaller outboards, the trim angle is adjusted manually by
moving an adjusting rod to different holes in the mounting bracket. The bigger outboards usually have a Trim Switch fitted on
the remote control level.
Install the part 27 as the above picture, shows. Before assembly, loose the part 37, fix the part 27 and 38 by tool 41, assembly
the 4pcs part 42 as the above picture shows. Then fasten part 42 and part 37. Make sure the part 37 can move appropriately
after part 37 and 42 been fastened.
Install the well-assembled out-board engine to the
board of the boat. Fix it tight
Loosen 2 screw 37 in
the above picture could
adjust the angle of the
outboard motor.
