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.
Loose 2 screw 37 in the above picture could adjust the angle of the outboard motor.
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, and then fasten part 42
and part 37. Make sure the part 37 can move appropriately after part 37 and 42 been fastened.
