General Information

Please read and retain the manual. The information in the manual describes the proper procedures for safely installing and maintaining your motors.

The description and specifications contained herein were in effect at the time this manual was approved for printing. Every effort has been made to ensure the accuracy of this document. Due to ongoing product improvement, Lenco Marine cannot guarantee the accuracy of printed material after date of publication.

Safety and operating information that is practiced along with good common sense can help prevent personal injury and product damage.

Safety
Do not modify the system in any way or add accessories not intended for regular use. Always disconnect power from motor when replacing props, removing debris around props, charging batteries, trailering boat or when the motors are not in use.

Wire and Cable Routing Recommendations
Troll’n Tab wiring should be installed according to wiring diagrams within this manual and should remain independent of all other electronics.

Extending any wiring associated with the Troll’n Tab system is not recommended.

Battery Recommendations
12-volt Deep Cycle batteries (Group 27 or higher).

The deep cycle trolling motor batteries should be isolated from the main engine battery. Sensitive electronics, depth finders in particular, should be connected directly to the main engine battery.

WARNING
Batteries contain sulfuric acid, which can cause severe burns. Avoid contact with skin, eyes and clothing. The battery also produces hydrogen and oxygen gases when being charged. This explosive gas escapes through the fill vent cell caps and may form an explosive atmosphere around the battery for several hours after it has been charged. Electrical arcing or flames can ignite the gas and cause an explosion that may shatter the battery causing serious injury.

Installation Instructions

Warning: The following instructions contain important safety information and should be followed carefully. Failure to do so may result in injury and will void warranty.

Please Read Complete Instructions Before Starting Application!

Tools and Materials List

• Electric drill
• Wire crimper/cutter
• 3/16" & 3/8" (.48 & .95 cm) drill bits
• Tape measure
• 7/16" (1.11 cm) wrench
• Small hammer
• 4' (1.22m) level/straight edge
• 3M 5200 Adhesive Caulking
• 2" (5.08 cm) hole saw
• #2 & #3 Phillips screwdrivers

1. Begin by first deciding where the trolling tab kit will mount. Note: When laying out desired tab location, hold tab against transom 3/8" (.95 cm) up from bottom of transom in line with hull. Make sure not to mount inside corner of hinge within 2" (5.08 cm) of a strake edge. If this is not possible, move tab so as to cover strake edge (see Fig.1).

2. Using the 3/16" (.48 cm) drill bit, drill hinge holes to a depth of 1-1/4" (3.17 cm). When drilling tab and bracket holes, you may drill through the transom; the screws will seal the holes when inserted. All screws and fasteners are stainless steel. Do not use any other type of metal. We recommend using 3M 5200 adhesive caulking to bed the hinge and screws. Next, mount the hinge to the boat using the 1-1/4" (3.17 cm) stainless steel sheet metal screws.

3. Attach the actuator to the upper mounting bracket using the 5/16" (.79 cm) stainless steel hardware provided. In order to position upper bracket against transom, you must lift trim tab so that the trailing edge is approximately 5/8" (1.59 cm) above a straight edge held to hull. This 5/8" (1.59 cm) measurement is for all tabs that have a trailing edge 9" (22.86 cm) off of the transom. If the trailing edge is 12" (30.48 cm) off of the transom, lift the tab so there is 3/4" (1.9 cm) between the tab and the straight edge (see Fig. 2). When the tab is at the appropriate level, use the two outside holes of the upper bracket as a guide to mark mounting location. Mount upper bracket where it lays naturally against the transom to prevent binding during travel. (Do not adjust the upper bracket to the right or left, this will cause binding.) Remove upper bracket from actuator to mark upper screw hole. Drill 3/16" (.48 cm) holes 2-1/4" (3.17 cm) deep.

4. Warning: With some installations, fuel, water tanks or other systems may prevent the actuator wire from entering the hull through the upper mounting bracket. Be sure to check inside hull before drilling 3/8" (.95 cm) wire hole. Using the center hole in the upper mounting bracket as a guide, mark the wire hole. If all is clear, use the 3/8" (.95 cm) drill bit and drill a hole through the transom. Drill completely through the transom. Pass the actuator cable through. Remove slack on wire into hole and seal with clear caulking or 3M 5200. Mount upper bracket using the three 2-1/2" (6.35 cm) stainless steel sheet metal screws. (We recommend using 3M 5200 adhesive caulking to bed the screws and bracket. DO NOT OVERTIGHTEN. If, however, you are prevented from drilling hole through bracket, simply drill a 3/8" (.95 cm) hole 4" to 5" (10.16 to 12.7 cm) above waterline and insert wire. Cover hole and wire with a clamshell vent sealed with clear caulking for a waterproof and finished effect.

5. At the helm, find a good location for the tactile switch and cut a circular opening using a 2" (5.08 cm) hole saw. Before cutting make sure the area inside the helm is clear of wires and other equipment that could be damaged. Using the template located in the owner’s manual on page 35, mark each stud and drill four 3/16" (.48 cm) holes through the helm. If the thickness of the helm is less than 1-1/4" (3.17 cm) secure the switch with the nylon nuts provided. If the thickness of the helm exceeds 1-1/4" (3.17 cm) apply a marine grade silicon sealer to each of the four drilled holes, to each stud and around the back of the tactile switch. Secure the switch and allow sealer to dry. When mounting the black control box, keep in mind that there is a three-foot lead that attaches to the back of the tactile switch. Make sure control box is mounted with wires facing down toward deck. Refer to trim tab wiring diagram on page 7. Be sure to mount the control box with the wires facing down toward the deck.

6. Following the trim tab switch wiring diagram, pull the 25' (7.62 m) actuator wires to the trim tab control box location. Be very careful of sharp edges that may damage the cable. Hook up according to diagram. Remember the left switch controls the right starboard tab and the right switch controls the left port tab.

7. With the trim tabs operating as described, you are now ready to wire the trolling motors, batteries and control box. First, select a place to mount the control box that allows access to on/off switch. As an option, control box may be mounted in the console.

8. Next, run trolling motor leads to the terminal strip. You may run leads through the splash well drains on either side of the engine, then into the rigging hatch with the engine control/steering cables. Attach wires to terminal strip according to wiring diagram provided. If splash-well drains are not an option, you may need to drill a 1/2" (1.27 cm) hole 4" to 5" (10.16 to 12.7 cm) above waterline and insert wire. Cover hole and wire with a clamshell vent sealed with clear caulking or 3M 5200 for a waterproof and finished effect.

9. When wiring from batteries to the control box, use a minimum of #6 AWG wire. Also, note that the 24V power lead is fused near the positive battery terminal. Fuse is 60-amp maxi fuse. Warning: Use of fuses larger than 60-amp could result in damage to system and will void warranty. For replacement fuse, call your local auto parts retailer or call Lenco Marine, Inc. for assistance.

10. To install trolling motor propellers, insert cotter pin through trolling motor shaft. Place the prop onto trolling motor shaft and line up the back of the prop with the cotter pin. Using the nylon prop nut provided secure prop to motor.

****ATTENTION INSTALLER****
After you tighten the nuts on the props, be sure to install two #4 screws into each prop nut. Failure to properly secure prop nuts with two screws on each prop will result in lost props when motors are reversed. Also make sure 4 nuts for motor bracket are secure to prevent the motor shifting in its housing.

11. *SPECIAL APPLICATION*

In the event of a recessed pocket application, use of shims behind the upper bracket may be necessary to prevent actuator binding during extension. You can adjust the actuator in the lower channel holes to obtain the 5/8" (1.59 cm) up dimension.

PLEASE FOLLOW THE INSTRUCTIONS AND DRAWINGS CAREFULLY.
