Finding the Best Mounting Location
1 Create a list of all suitable mounting locations for the CCU.
Suitable mounting locations should not be within 60 cm (2 ft.) of the following:
• Iron
• Magnets
• High-current wires
• Intermittently-running pumps, such as head pumps and live well pumps
A large magnet, such as a subwoofer-speaker magnet, should be no closer than 1.5 m (5 ft.) to any of the
mounting locations.
2 Locate the center of rotation of the boat, and measure the distance between the center of rotation and each
of the suitable mounting locations you listed in step 1.
3 Select the location closest to the center of rotation.
If more than one location is approximately the same distance from the center of rotation, you should select
the location that best meets these considerations.
• The best location is closest to the centerline of the boat.
• The best location is lower in the boat.
• The best location is slightly forward in the boat.
Testing a Location for Magnetic Interference
You can use a handheld compass to test a mounting location for magnetic interference.
1 Hold a handheld compass in the CCU mounting location.
2 Move the compass six inches to the left of the location, then six inches to the right, observe the needle, and
select an action:
• If the compass needle moves more than three degrees during this step, magnetic interference is present.
Select a new mounting location and repeat the test.
• If the compass needle does not move, or moves less than three degrees, proceed to the next step.
3 Repeat this process while moving the compass above and below the mounting location.
4 Repeat this process while moving the compass in front of and behind the mounting location.
ECU Mounting and Connection Considerations
• The ECU can be mounted on a flat surface, facing any direction.
• Mounting screws are included with the ECU, but you may need to provide different screws if the supplied
screws are not suitable for the mounting surface.
• The ECU must be mounted in a location where it will not be submerged or exposed to wash down.
• The ECU power cable connects to the boat battery, and it can be extended if needed
