Improper installation of this kit could result in personal injury due to loss of boat control.

Only shift the engine while at idle RPM. The tiller handle features a mechanical system that will not allow the engine to be shifted into gear above idle. If the shift into gear is accomplished at a high rate of speed, the RPM limit will be released and the resulting sudden acceleration could injure boat occupants and bystanders.

A boat designed for remote steering might have a lower maximum rated horsepower for a tiller-steered outboard than shown on the certification plate. To avoid overpowering a boat designed and rated for remote steering, contact the boat manufacturer for the tiller steered maximum rated horsepower.

To prevent accidental starting while servicing, disconnect battery leads from the battery. Twist and remove all spark plug leads.

Avoid damaging the tiller handle when tilting the motor up. Position the motor to clear obstacles in the motor well and boat.

Steering Damper Installation


Grease link rod with Triple-Guard® 0508298 grease and slide into tilt tube.

Place flat washer and rubber washer on starboard end of link rod.

Place flat washer, spacer, and rubber washer on port end of link rod.

Install link arm on starboard end of rod as shown. Temporarily fasten arm to rod with flat washer and locknut.

Temporarily fasten other link arm to port end of steering damper assembly with flat washer and locknut.

Grease shoulder of drag link bolt with Triple Guard grease. Install two bushings in drag link hole. Fasten drag link to bracket using bolt and locknut. Torque drag link bolt to locknut 24.3 ft. lb. (33 Nm).

Fasten drag link bracket and drag link to cylinder assembly using two screws. Apply Nut Lock™ and torque 88.5 to 142 in. lb. (10 to 16 Nm).

Insert the starboard end of steering damper plunger rod into starboard link arm, inserting port link arm onto rod at the same time. Using flat washers and locknuts, temporarily fasten port link arm and starboard link arm.

Place bushing in drag link hole with flange facing steering arm. Grease shoulder of drag link bolt with Triple Guard grease. Install bolt in drag link through bushing and thread bolt into steering arm rear hole as shown. Thread bolt until drag link is against steering arm. Temporarily tighten the washer and nut to the bolt.

Torque four starboard and port link arm locknuts to 24.3 ft. lb. (33 Nm).

Torque drag link bolt and locknut to 24.3 ft. lb. (33 Nm).

Never reuse the locknut after it has been threaded into position and torqued. After initial use, the locking ability of the nut is diminished. A reused locknut could loosen resulting in a loss of steering control and creating a risk of personal injury or property damage.

Steering Damper Adjustment


The steering damping force can be adjusted by turning the knob on the steering damper.

  • Turning clockwise: Increases damping force.

  • Turning counterclockwise: Decreases damping force.

Adjustable range of steering damper is five turns. Do not turn past locked position as the damper may not function properly, creating a risk of personal injury.
