Before you start
- If factory setting calibration or parallel calibration has not been performed, gear cannot be engaged.
- Drive leg calibration must always be carried out in accordance with the instructions.
Procedure
- Ensure the boat is out of the water and batteries are fully charged.
- Connect the switch box 3809562/3887101 to the starboard and port engine diagnostic connectors and to the VODIA tool.
- Perform Drive leg factory setting calibration first (sets starboard and port drive leg end positions).
- Then perform Drive leg parallelism calibration.
- Push the plastic cylinders into the exhaust outlets of both drive legs.
- Place the aluminum bar in the port cylinder and align the drive until the bar aligns with the starboard cylinder hole.
- Move the bar to the starboard cylinder and repeat until it aligns with the port cylinder hole.
- When the bar moves freely through the cylinder holes the drive legs are parallel to the boat keel.
- Report the calibration on the VODIA website after finishing.
