Step 5: Installing Hydraulic Tubing
1. Guide the blue and black hydraulic tubing through
the black mesh tubing cover
M
.
Note: The black mesh tubing
M
cover may need to
be trimmed to length.
WARNING: Keep debris out of the hydraulic tubing.
Use the red end caps provided at all times while
routing the hydraulic tubing throughout the boat.
Debris in the tubing will cause damage to the HPU.
Step 5: Continued
2. At this point, the hydraulic tubing may be routed
in one of two ways. It may be routed either over
the transom or through the transom using the (2)
supplied thru-hull bushings
K
. If the hydraulic tubing
is not being installed through the transom, route
the tubing to the HPU as per your preference, and
proceed to Step E. If the hydraulic tubing is to be
installed through the transom, holes will need to be
drilled for the thru-hull bushings
K
.
Note: When choosing a location for the holes, ensure
that the tubing will form a natural curve when
leaving the stern bracket, and that the transom
holes will be above the water line.
3. First, drill pilot holes in the transom with a 9/64” drill
bit for each of the (2) thru-hull bushings
K
. Then,
drill out both pilot holes with an 11/32” drill bit. Once
the holes are drilled, insert the (2) thru-hull bushings
K
, and route the tubing to the HPU. (See Figure #4)
Note: Be sure to allow an adequate amount of slack in
the hydraulic tubing between the stern bracket and
the point that the tubing enters the vessel. This will
provide slack in the hydraulic lines to allow for full
up and down operation.
4. The tubing is now ready to be attached to the HPU.
Route the tubing according to your preference, and
trim the excess using a razor tubing cutter. All cuts
made in the tubing must be as straight as possible to
ensure that the compression fittings do not leak.
Note: For ease of future maintenance, leave enough
excess hydraulic tubing such that the HPU can be
moved out of the compartment with the tubing still
attached.
5. While taking note of their orientation, remove the blue
and black dust caps from the hydraulic compression
fittings on the HPU.
6. Disassemble both of the compression fittings by
removing their nuts and ferrules. With both the
blue and black hydraulic tubing cut to length, feed
each through a compression fitting nut as well as a
compression fitting ferrule. (See Figure #5)
Note: The tubing needs to pass through the ferrule far
enough such that there is approximately a
1/2” length of tubing exposed. (See Figure #5)
Step 4: Continued
6. Unravel the red and black wires on the HPU. Route
the red wire to a 12 volt positive source via a battery
switch, and route the black wire to a 12 volt negative
source via a common ground post.
Prior to cutting the excess wire, ensure that there is an
adequate amount of slack such that they may be
easily disconnected in the future.
7. Once the wires have been trimmed to length with wire
cutters, install the (2) ring connectors
J
using wire
strippers and wire terminal crimpers.
8. Heat the (2) ring connectors
J
with a heat gun until
their respective jackets shrink completely and adhere
to the wires.
DO NOT CONNECT the red or black wire at this time.
These wires will be connected once the hydraulic
tubing is installed.
