Most models have built-in lights which will require routing the wire or wires to your power source. To assure a clean
installation you may want to wait and drill the routing holes after you are satisfied with the compass alignment.
Specific model installation instructions are as follows :
Note for all flush and bulkhead mount compasses:
It is important that you use the mounting gasket included with each model. We do NOT recommend the use of
bedding compound since some brands contain chemicals that could damage the plastic dome.
F-50 & F-50W Flush Mount
Using the mounting template supplied with the compass, make the cutout in your chosen location and mount as
instructed above (Mounting the Compass). Note: If you cannot access the compensation rods from below you need
to allow for easy removal of the compass during compensation. (See Compensation instructions below).
V-57, V-57.2 V-57W & V-57W.2 Dash Mount
This model requires a 3-inch diameter cutout in the dash. Install the mounting flange, with the mounting gasket, in the
cutout and secure it from behind the dash using the mounting hex nut. Be sure that the light is located at the exact
bottom. Next, locate the compass capsule in the mounting flange such that the bowl (the white ring around the middle
of the capsule) is approximately level. Lightly secure the capsule in place using the “O”-ring and the screw-on bezel.
Make the final adjustment so that the capsule is perfectly level and then firmly secure the capsule in place using the
screw-on bezel.
B-51, B-51G, B-51W, B-51-A & RA-91
The bracket model can be mounted on either a vertical or horizontal surface. Using the bracket as a mounting
template, install the bracket in the mounting area at exactly a ninety-degree angle to the centerline of the boat. The
compass can now be mounted into the bracket using the two thumbscrews.
D-55 Deck Mount
Depress the button at the bottom rear of the compass to remove the base from the compass. Using the base as a
template mount as instructed above (Mounting the Compass). (Be sure to remove the night light from the base and
install it into its slot in the compass before installing the compass on the base.)
S-53, S-53G, S-53W, S-53-A & RA-93 Surface Mount
Remove the base by “squeezing” the buttons on the side of the housing while carefully pulling on the base. Mount the
base as instructed (see Installation above). Re-install the compass and begin compensation (see Compensation
instructions below). Note: the mounting holes for this model are slotted, so by centering the mounting screws within
the slots you can install all screws and make your alignment corrections later.
Mounting pads are provided if you do not wish to drill any holes. Remove the mounting pads from their backing and
stick them over the mounting slots. Because alignment is difficult to verify at this time we suggest temporarily
securing the base (masking tape works well)
until after compensation. After alignment has been verified, make a
small pencil mark at the front and back of the compass and deck. Remove the remaining backing from the pads and
secure the base to the deck using the pencil marks as a reference.
Note: The light wire can exit the compass either through the back or down through the bottom.
Night Light Wiring (all Models)
All models are supplied with a 12-volt night lighting system. To connect lights to a 6 or 24-volt system, alternate bulbs
are available. Contact the factory with your model and serial number for a part number and price.
Tel. 781-826-5131 Fax. 781-826-7336 E-mail service@ritchienavigation.com
Lights should be wired to an appropriately fused 12-volt circuit in your electrical system (i.e. running light circuit).
Connect one wire to ground and one to positive, observing polarity is not necessary with Explorer compasses.
