Components

1. Fuel joint cap

Manual starter handle

Used to crank and start the engine.

1. Steering friction adjuster

To increase resistance, turn the steering

friction adjuster clockwise.

To decrease resistance, turn the steering

friction adjuster counterclockwise.

Trim rod (tilt pin)

The trim rod (tilt pin) is used to adjust the trim

angle of the outboard motor in relation to the

angle of the boat transom.

1. Manual starter handle

Steering friction adjuster

WARNING

Do not overtighten the steering friction

adjuster. If there is too much resistance,

it could be difficult to steer, which could

result in an accident.

The steering friction adjuster provides adjust-

able resistance to the steering mechanism,

and can be set according to operator prefer-

ence. The steering friction adjuster is located

on the port side of the outboard motor.

1. Trim rod

Tilt lock mechanism

The tilt lock mechanism is used to prevent the

outboard motor from lifting out of the water

when the gear shift lever is in the

reverse position.

When the gear shift lever is moved to the

reverse position, the tilt lock mechanism

operates to prevent the outboard motor from

being tilted up.
