DOMETIC SA27252P Dual Outboard Kit

Product Information

Specifications

• Part Number: SA27252P
• Compatible with Johnson and Evinrude motors 35 HP and up

Product Usage Instructions

Preparation for Installation

1. Follow the motor manufacturer’s instructions and ABYC safety standards for small craft to install and place the outboard motors on centers.
2. Set both motors in a dead-ahead position and adjust for any toe-in or toe-out as per the motor manufacturer’s instructions.
3. Measure the center-to-center distance between attachment holes in the tiller arms. Subtract 1-3/4″ (44 mm) from that dimension to determine the proper tie bar length.
4. Cut the tie bar (item 1) to the proper length, taking care not to damage the threads. File the lead of the thread if necessary.

Tie Bar Assembly

1. Refer to Figure 2. Thread one hex nut (item 2) onto each end of the tie bar (item 1), leaving approximately 2″ (50 mm) of thread exposed.
2. Fully thread the rod end (item 3) onto each end of the tie bar,  then back off equally until the holes in the rod ends align with the tiller arm attachment holes. Do not exceed three full turns on each end.
3. Run the hex nuts up against the rod ends. Grip the rod ends with vise grips or a similar tool, and torque the hex nuts securely against the rod ends to prevent unthreading.

Tie Bar Assembly Installation

1. Place the tie bar assembly beneath the tiller arms, following the configuration shown in Figure 2. Ensure that the tie bar assembly is mounted in the outer holes of the Johnson/Evinrude tiller arms. The inner holes (closest to the motor) are for steering cable linkage.
2. Install one flange head bolt (item 4) upward through each rod end as shown, and thread them into the tiller arm attachment holes.  Thread on the locknuts (item 5) and torque the hardware to a  minimum of 200 in. lbs. Do not exceed 250 in. lbs.

The installation is now complete.

Maintenance Notes

1. After a few hours of operation following the installation, and periodically thereafter, re-torque all fasteners and check the steering for security and integrity.

FAQ

• Q: Who should install this kit?
  A: This kit should be installed by an expert marine mechanic.

  A: After the initial installation, and periodically thereafter, re-torque all fasteners and check the steering system for security and integrity.

Dual Outboard Kit
Part # SA27252P

NOTICE!
Installer: These instructions contain important safety information and must be forwarded to the boat owner.

CAUTION!
This is a ‘custom’ kit and should be installed by an expert marine mechanic.

WARNING!

• Read these instructions thoroughly before beginning installation. Failure to follow these instructions or incorrect assembly could result in steering failure with subsequent personal injury and/or property damage.
• To obtain the best steering performance, the outboard motor or outdrive must be installed and lubricated and the trim tab adjusted by the motor manufacturer and the boat manufacturer’s specifications.
• Check the contents of this kit against the parts list on this instruction sheet. Use parts supplied only as instructed on this sheet. Do not substitute parts or components from other steering manufacturers. They may cause a safety hazard for which Dometic cannot accept responsibility.

This kit contains the parts required to link two outboard motor tiller arms in dual engine installations and is for use with Johnson and Evinrude motors 35 HP and up.

Preparation for installation

1. Outboard motors must be installed and placed on centers according to the motor manufacturer’s instructions and ABYC safety standards for small craft.
2. Set both motors in a dead-ahead position and adjust for any toe-in or toe-out by the motor manufacturer’s instructions. Measure the center-to-center distance between attachment holes in tiller arms. Subtract 1-3/4” (44 mm) from that dimension to arrive at the proper tie bar length.
3. Cut tie bar (item 1) to the proper length, taking care not to damage the threads. Dress lead of the thread with a file if necessary.

Tie bar assembly

1. Refer to figure 2. Thread one hex. nut (item 2) onto each end of tie bar (item 1) leaving approximately 2” (50 mm) of thread exposed.
2. Thread rod end (item 3) fully on to each end of tie bar, then back off equally until holes in the rod ends align with the tiller arm attachment holes.
3. Run hex. nuts up against rod ends, then gripping rod ends with vise grips or a similar tool, torque hex. nuts securely against rod ends to prevent unthreading.

Description

CAUTION!
When torquing hex. nuts, rod ends must be kept in a parallel plane to allow for maximum pivoting during independent tilt and turn of motors.

Tie bar assembly installation

1. Place tie bar assembly in position beneath tiller arms as shown in figure 2. Johnson/Evinrude tiller arms have two attachment holes. The tie bar assembly must be mounted in the outer holes. The inner holes (closest to motor) are for steering cable linkage.
2. Install one flange head bolt (item 4) upward through each rod end as shown, and thread it into the tiller arm attachment hole. Thread on locknuts (item 5) and torque hardware to 200 in. lbs. minimum. Do not exceed 250 in. lbs.
   The installation is now complete.

CAUTION!
Operate each engine independently through tilt and turn range to ensure that no binding occurs.

WARNING!
The boat should be operated with caution until the steering system has been thoroughly checked out under normal operating conditions to ensure that the installation is correct and complete.

Maintenance notes

1. After a few hours of operation following installation of this kit and periodically thereafter, re-torque all fasteners and check the steering for security and integrity
   WARNING!
   Loosening or separation of one or more fasteners may cause failure of the steering system, resulting in property damage and personal injury.

2. Inspect periodically for corrosion. All metal parts meet or exceed applicable specifications for corrosion resistance. However, with extended operation under extreme conditions, corrosion may occur and affected parts should be replaced
