Adjustment of outboard motor

Damping force adjustment of throttle control handle

When the adjustment screw is turned clockwise, the damping force will increase, and when it is turned counterclockwise, the damping force will decrease

Adjustment of steering damping force

When pushing and pulling the control arm by hand to turn the boat, the damping force can be adjusted according to the needs of the operator. The adjustment method is to turn the adjusting bolt on the side of the rotating bracket clockwise to increase the damping force of the swing, and rotate it counterclockwise to reduce the damping force; (see Figure 2)

Adjustment of throttle linkage mechanism

(1) Turn the idle speed throttle limit screw to the position where the compression spring is in the free state;

(2) Rotate the joystick, install the first throttle cable in the roller groove in the state of pulling on the outside, and install the other one on the inside to send;

(3) Loosen the lock nut and adjust the length of the throttle cable until the two steel cables can be fully opened when the joystick is turned and the throttle can be in a free state when returning;

(4) Starting the engine "neutral" idle speed control is within the range of 1300 rpm ~ 1400 rpm, if the engine speed is too low, you can use the tool to adjust the carburetor idle speed screw clockwise, if the engine speed is too high, then on the contrary.

(5) The adjustment of the combustible mixture at engine idle speed is mainly based on the working stability of the engine at idle speed at the time and the ambient temperature. The general ambient temperature is high, and the mixture concentration can be appropriately adjusted to lean. Use the random tool to turn the mixture adjustment screw counterclockwise. 1/4 circle, observe the idling stability of the engine, and vice versa.

Spark plug inspection and electrode gap adjustment

The recommended spark plug model is: NGK BR7HS-10 T0RCH E7RC, and the electrode gap is 0.9 to 1.0 mm.
