1. Hold the power
unit HORIZONTALLY in the desired location. Using the power unit bracket
as a template, mark the three installation holes and the drill 5/32" holes
1" deep. (figure 7)
2. Before securing
the power unit, fill the reservoir with automatic transmission fluid.
3. Remove the hydraulic
power unit circuit board cover. Insert the digital display touch
pad cable end plug into the power unit circuit board. Waterproof
the connection with WD 40 or equal.
PROCEDURE 5:
HYDRAULIC LINES AND SENSOR WIRES
1. Remove the clevis pin
from the transom bracket and move the cylinders away from the transom bracket.
Route the sensor wires from each cylinder through the hole in the transom
to the power unit.
2. Route a length
of hydraulic line from the left control valve (see Figure
7 to the left trim tab. Cut the hydraulic line square to length
with a sharp knife or razor blade.
3. Slip the NUT
and SLEEVE over the hydraulic line and push the TUBE SUPPORT fully
onto the end of the line (refer back to figure 6).
Push the end of the hydraulic line onto the cylinder fitting and hold firmly
in place. Slide the sleeve and the nut down the line and hand tighten
the nut onto the fitting. Tighten the nut just until it is snug.
Repeat this process with the hydraulic line from the right control valve.
NOTE: The holes
through the transom will be sealed during procedure 9. It is extremely
important to completely seal the hole in the transom on both the left and
right tabs. If these holes are not completely sealed, leakage may
occur. Use a quality marine adhesive/sealant. Check for leaks
after placing the boat in the water.
4.
Route the sensor wires to the hydraulic power unit. Secure the sensor
wires to the corresponding hydraulic hose. Temporarily connect the
wires from the power supply as indicated in Figure 8. (If you connect
to the wrong cylinder, you will immediately know it when you start the
calibration procedure and can correct them at that time.) |

SAFETY
NOTE
Make sure the hydraulic
lines and wires are routed away from all sharp edges and are tied and supported.
CONSULT YOUR MARINE DEALER OR A TRAINED MECHANIC IF YOU AE NOT SURE OF
THIS PROCEDURE.
PROCEDURE 6:
DIGITAL DISPLAY TOUCH PAD
1. Route the digital
display touch pad cable from the hydraulic power unit to the boat's control
console. A 1" clearance hole is required for the connector body when
routing through bulkheads. The touch pad should be mounted close
to the steering wheel within easy reach and within the first line of sight
of the operator. Tape on the touch pad template and drill four (4)
7/64" diameter holes and one (1) 1 1/4" clearance hole.
2. Plug the cable
into the back of the touch pad. Secure the cable in place so that
it will not accidentally pull the plug out. Coat the connection with
WD 40 or equal to protect against moisture.
3. Screw the panel
into position and attach the red wire lead to the fused 12 volt positive
terminal of the ignition, or accessory switch that is "on" during normal
use. Attach the orange lead to the 12 volt connection of the navigation
light switch. This will provide illumination of the display panel
whenever the navigation lights are on (Figure 9).
PROCEDURE 7:
WIRING TO POWER SUPPLY
| 1.
Using a red 14 gauge wire, connect the red 12 volt lead from the hydraulic
power unit to or close to the positive 12 volt battery terminal using a
20 amp fuse or breaker to provide the circuit. Connect the black
ground wire to or close to the negative battery terminal. (Figure
10) |
|
2. Make sure the hydraulic
connections have been tightened on both the control valves and the cylinders.
PROCEDURE 8:
TOUCH PAD DISPLAY AND CALIBRATION PROCEDURE
1. Run the trim
tabs all the way down and then all the way up one at a time by pushing
the DOWN and UP buttons on the digital display touch pad. Check for
fluid leaks at each cylinder's brass fitting at this time. You should
hear the pump load up when the trim tab is all the way down.
2. With both trim
tabs all the way up, add automatic transmission fluid to within 1/2" of
the fill hole. (some of the fluid will stay in the cylinder).
NOTE: DO NOT ADD
THE FLUID WHILE THE TRIM TABS ARE IN THE DOWN POSITION BECAUSE THE FLUID
WILL OVER FLOW INTO THE BOAT WHEN THEY ARE UP.
3. Locate the four
(4) adjustments on the electronic circuit board at the hydraulic power
unit. (refer back to Figures 7 and 8)
NOTE: The adjustment
screws are numbered 
Each screw turns to the
left (counter clockwise) to about 7:30 and to the right (clockwise to about
4:30. Be gentle with the adjustments and turn the other way if you
are
not sure about the stops. Screws 4 and 3 adjust the right side while
screws 2 and 1 adjust the left side (see Figure 8).
(1)
Start with the trim tabs in the UP position.
(2)
Turn screws 1 and 3 to the midway point which is about 12:00.
(3)
Turn screws 2 and 4 to 7:30 and then turn to the right just past 01:01
to 00:00 (do not keep turning when you first get 00:00.
(4)
Run the trim tabs to the DOWN position.
(5)
Turn screws 1 and 3 to 20:20.
(6)
If necessary, fine tune the 00:00 UP position with screws 2 and 4 and the
20:20 DOWN position with screws 1 and 3.
WITH THE SYSTEM IN WORKING
ORDER, PERMANENTLY CONNECT THE CYLINDER SENSOR WIRES AT THE POWER UNIT.
If you have a problem
calibrating the system, proceed as follows:
(1)
Disconnect the sensor wires where you connected them at the power supply.
(2)
Turn all four screws to 7:30 and the display should read 39.39.
(3)
Short out like colors of sensor wired. The 39s should turn to 00s.
(4)
Check the cylinders with an ohm meter at the hydraulic power unit where
the wires were disconnected. The resistance of each cylinder should
be less that 1000 ohms in the up position and less that 5000 ohms in the
down position.
PROCEDURE 9:
SEAL THE HOLES WHERE THE HYDRAULIC LINES AND SENSOR
WIRES ARE ROUTED THROUGH THE TRANSOM.
1. With the trim
tabs in the DOWN position, pull the clevis pin from the mounting bracket
and pull the hydraulic hose out one inch.
2. Fill the center
hole in the transom bracket hole that the hydraulic lines comes through
with 3M 5200 or equal. Continue filling as you move the piston rod
back the 1" and install the 1/4 "clevis pin. (the adhesive/sealant
will follow the hose in the transom fitting.) Secure the clevis pin
with the cotter pin. Pack additional sealer around the hydraulic
line and behind the clevis pin.
PROCEDURE 10:
BOOT INSTALLATION
1. Nylon hose clamps
are used at the top and the bottom of the boot. Tighten the clamps
with a pair channel lock (wide mouth) pliers. Remove the clamps by
inserting a screwdriver and prying in a manner to cause the teeth to slide
sideways in opposite directions.
2. Apply quality
marine grease around the transom fitting and then hook the boot over the
transom fitting. (grease is used to seal the fine pores in the transom
fitting and yet allow easy removal of the boot when required).
3. Hold the boot
against the transom and install a nylon hose clamp around the transom fitting
making sure it grabs the boot. NOTE:
If the nylon clamp will not work, you probably have an older style transom
fitting. In this case, cut or grind the nylon clamp down 10 1/4 :,
or substitute a 3/16" nylon tie strap.
4. Slide the boot
up about 3" above the drain hole in the underside of the cylinder and rub
grease on just below the boot. Then, slide the boot down to 2" above
the hole and install the nylon clamp 1/2 " up on the boot. If there
is no flat flange over which to install the clamp, make a flat surface
by stretching electrical tape over the first high ridge and then install
the clamp over the tape.
NOTE:
The 5/16 bolt that is in the cylinder drain hole should be removed periodically
while the tabs are in the DOWN position to see if the boot was sealed properly.
Drain water if present and re-seal the boot.
NOTE:
If the boot is sealed properly, it may dimple a little in the down position
and balloon a little in hot weather. This is normal and is not a
matter of concern.
OPERATION
HINTS
Here are some basic operational
instructions for the Trim Tabs System. As you become proficient with
the trim adjustments you will appreciate the advantages of the tab position
indication system even more.
UNDERSTANDING
THE DIGITAL DISPLAY PAD READOUT
Actual size is 4 1/2" x 3 1/2"
| The touch pad displays
a readout of the trim position in degrees from zero (0) to twenty
(20) for the port and starboard tabs simultaneously. When both tabs
are in the full Up position, the display will read 00:00. This shows
that the port tab is in the (00) position and the starboard tab is in the
(00) position. If you move the port tab all the way down the digital
display will read 20:00. This indicates that the port tab is in the
(20) position and the starboard tab is in the (00) position. With
both tabs all the way down the display will read (20:20). You can
set each tab to any number from (00) to (20) by pushing the UP or DN (down)
buttons. Pushing the UP button reduces the number readout; pushing
the DN button increases the number readout. The higher the number,
the greater the trim action. |
 |
HOW TO USE THE TRIM TABS
1. At the dock make
sure that the display reads (00:00). This will prevent damage to
the tabs around shallow water or cradles.
2. Once clear of
obstacles, and prior to adding power, adjust the tabs and note the performance
of the hull. If the hull moves out of the water easily to planing
speed, (10:10) is the correct initial setting. If the hull does not
plane easily, add more trim to (15:15) and note the results. If the
hull immediately rides bow down, reduce trim to (05:05) and note the results.
The idea is to make adjustments that result in the hull reaching a planing
condition smoothly, quickly, and without bow high transom low condition.
3. Once the hull
is on plane, reduce the trim to a setting that will allow the hull to stay
on plane at the desired power setting.
4. If the boat does
not ride level on the roll axis, add trim to the low side until the ride
is level. You an also reduce trim on the high side if adequate trim
remains to pull the hull on plane.
5. Adding trim in
rough seas can reduce pounding.
6. Cavitation can
be reduce with trim.
7. In quartering
seas and/or quartering wind add trim and maintain a level attitude in the
same manner as #4.
You will find many uses
for your trim tabs. Sea, wind and loading conditions are infinitely
variable. You can master these conditions with your trim tabs and
a basic understanding of how to use them.
TRIM TABS IMPROVE YOUR
BOATS PERFORMANCE
Trim tabs are, in effect, movable extensions of the planing hull.
With the "extended" hull, you can attain greater speed and stability in
virtually all running conditions. The trim tabs can increase boat
speed by allowing the hull to plane at lower power settings. They
can also decrease boat speed (for trolling, docking, and following seas)
as well as improve steering at slow speeds by reducing wandering of the
boat. The ability to move each trim tab by remote control adds a
new dimension to boat performance. Furthermore, with the digital
touch pad display, you know each of the positions of each tab.
Trim tabs can also help you save fuel! You should be able to reduce
the power required to maintain a fixed hull speed. You may even be
able to switch to a higher pitch prop.
This all means that your boat will perform more smoothly at increased speed
with a reduced fuel consumption and greater comfort and control.
Instead of raising up to look out over the bow or moving people up front
and from side to side to balance the boat, simple move your trim
tabs up or down. It adds a whole new dimension to the pleasure and
safety of boating.
After installing your
system if you have trouble trying to figure out how to use it you may contact
us.
