Jack Plate Transom Side Jack Plate Motor Side Relay Pack Switch
Welcome to the Atlas World. You have purchased the best Hydraulic Jack Plate that is available. When
installed correctly, this plate will give you many years of trouble free use.
NOTE: T-H Marine recommends installation by a full service marine dealer to insure proper fit and
trouble free operation. We cannot assume any liability for improper drilling of transom or damage due
to improper installation. This Atlas is designed to accommodate V-4 and V-6 engines only, with a
maximum horsepower rating of 300 HP.

INSTALLATION INSTRUCTIONS
Step 1:
If no outboard engine is mounted to transom skip to Step 3.
Step 2: If outboard motor is mounted to transom remove engine using proper lifting equipment and
procedures. Be sure the lifting equipment is rated for the necessary lifting capacity. See your local marine
dealer if unsure. Remove mounting bolts and nuts and carefully swing motor away from boat. It should not be
necessary to remove any cables or wires as most installations have adequate length. Disconnect any wires or
cables that do not have necessary length and obtain longer wires or cables for completion of installation.
Step 3: Prepare transom for mounting by removing any silicone residue, dirt or oil. Put a fresh and generous
bead of silicone around each mounting hole. Mount the Atlas jack plate to transom (shortest side 12 ½” long)
using the bolts and nuts from engine removal. If you did not have engine mounting bolts, you will need ½”
stainless mounting bolts and appropriate washers and lock nuts to fit the thickness of your transom. These
fasteners are available from your local marine dealer. It is necessary in our installation that the bolts go through
the transom then through the Atlas jack plate. The nuts attach to the bolts inside the jack plate. We recommend
use of a transom support plate for both the top and bottom mounting bolts, thus eliminating the possibility of the
bolt heads from becoming embedded into transom. T-H Marine Transom support plates are available from your
marine dealer and look like the picture below.
* NOT INCLUDED (OPTIONAL)
When mounting the Atlas jack plate to your transom, you will note that there are three sets of mounting holes in
the jack plate. Because transoms are different, three mounting hole patterns are pre-drilled. You choose which
best satisfies your transom and engine setup needs. However, make sure that you use same holes on both sides,
so jack plate will set level.
Step 4: Before mounting engine, the wiring harness will need to be hooked up. Locate desired position for
“Up & Down” rocker switch. Cut 1 ½” x 1” rectangle hole taking care to check for any wires, brackets or cables
behind dash for the switch to pass through. However, do not install switch at this time.
Step 5: The Harness Pack will contain a rocker switch, a relay pack and a switch harness. When you open
your harness the switch will not have any wires attached, but it will have three terminals to hook the three spade
connectors. There will be a black coated wire that is 20 ft long, on one end will be spade connectors on a
purple, green & blue wire. This is your cable that will run from relay pack to switch. This cable will need to
run from switch to your relay location, which should be near a power source, normally in the battery
compartment. (Note: The spade connectors go to the switch.)
Blue—wire goes to top of switch (UP)
Purple—wire goes on middle of switch (COMMON)
Green—wire goes to bottom of switch (DOWN)
Step 6: Even though the relay pack is water resistant, every effort should be made to locate this relay
assembly in a place that will be as dry as possible. It can be mounted with screws or cable ties. The RED wire
with the 40 amp ATC fuse goes to positive post of your battery. The BLACK wire goes to negative post of
your battery.
Now you are ready to plug in all other connectors. The connectors are arranged so they will only plug in one
way. The cable wire from the switch plugs into one connector, the motor wire from jack plate plugs into the
other connector.
Step 7: You are ready to test your plate. Run plate Up and Down a little at a time to make sure your wires
are correctly placed and not getting caught in plate. NOTE: If the switch does not work as marked after
your connections are made, then you can swap the blue and green wires to reverse the direction of
movement.
Step 8: If installing a gauge kit (available as an option from T-H Marine and your local dealer), we
recommend install the gauge kit sending unit before mounting the engine. See instructions with gauge kit for
proper installation.
Step 9: Outboard engine is ready to mount at this time. The engine will mount into selected hole pattern.
You will need (4) ½”-13 x 3” long stainless steel bolts, washers and nuts for this installation also. T-H
Marine’s Bolt Kit (BK-1-DP) is available from your local marine dealer for this use.
After engine is mounted, repeat Step 7 (above) to assure wire clearances and that your plate runs smoothly up
and down.
OPERATING INSTRUCTIONS
1. Never continue to hold switch in the up or down position after the plate has completed its travel in
that direction. Doing so will cause extra amp draw on your battery and could damage the motor
or pump on your jack plate and may burn out the fuse.
2. Always rinse your plate off after every use especially if used in salt water. Keeping the black
composite jack plate sides free of debris is important for smooth operation.
3. After each use, check all mounting bolts to make sure they are tight.
4. Check and clean any loose wires and connections.
5. If you do not have power to the plate, the first thing to check is the in-line 40 amp ATC fuse on
positive side of battery. If the fuse is blown, you’ll need to replace it with a 40 amp fuse.
However, something caused the fuse to blow. So if happens again, trouble shoot your electrical
system immediately and seek help from your marine dealer if necessary. The most likely causes
for the blown fuse are: (1) holding the switch down to long after the plate has completed travel in
one direction and (2) a short in the electrical wiring to the jack plate.
6. Always trailer with the jackplate in the lowest “down” position!
