MOUNTING THE CONTROL BOX
The control box MUST NOT be mounted too close to anything magnetic that will influence it, and the location should be
checked with a handheld compass before placing an order. See “How to check for magnetic interference” below. Only use
included 316 stainless fasteners for mounting the control box, other stainless alloys and fasteners can have a magnetic
field. For easy removal and servicing, cutting and splicing the control box cable is not recommended. If routing is
preferred, complete sea trials BEFORE cutting and routing the cable to make sure the mounting location is free of
magnetic interference.
Mounting the control box on the pedestal guardrail below the binnacle compass and shift levers often works well. This
location offers easy access and operation. It may also be mounted several inches above the ship’s compass card and to the
side (also on the pedestal guardrail). It must be at least 12
ʺ
-14
ʺ
above, fore, or aft of the standard motor box; if using a
vertical motor box it must be at least 18
ʺ
above or 12
ʺ
-14
ʺ
to the side. The lower part of the binnacle compass where
compensating magnets and engine levers are located will usually show a slight magnetic field.
Electric motors, radio speakers, tool boxes, winch handles, dive knives or fasteners can also cause interference if too close,
even on the opposite side of a bulkhead. Instrument screens, tablets and other
electronics are often magnetic as well.
The control box must be oriented level and facing either the bow or the stern of the boat.
The cable exits the bottom side of the box. If the control box does not face the bow or
stern of the boat, the autopilot heading will be affected by the boat pitching and heeling.
The short bracket is used to mount it to the pedestal rail (it can be tightened firmly
enough to allow swinging fore or aft during use if needed), or to a vertical bulkhead or
sidewall. The
long bracket is used to mount it to a horizontal shelf, console, or to hang
from an overhead. Only one bracket is included, let us know which is preferred at time
of ordering. Only use included 316 stainless fasteners.
Control Box Mounting Requirements
Note: Do not route cable until after successful sea trial
Mount the control box a minimum 12 inches above motor box and minimum 8-10
ʺ
below the binnacle compass or
several inches above it. If mounting the control box to a cockpit sidewall, do not mount it directly to port or starboard of
the motor box, mount it a minimum 12
ʺ fore or aft of the motor box; if using a vertical motor box at least 18 ʺ above it or
12
ʺ
to the side; this is to avoid interference from the motor’s magnetic field. A common cause of magnetic interference is
locating the control box too close to the motor box, ship’s compass, or engine control cables and parts that may have
become magnetized over the years.
