Chapter 6: Trolling Motor Mounting Installation

Invented in by O.G. Schmidt in 1934, trolling machines gave new turn to fashion of fishing and boating. These powerful trolling machines offered more thrust, speed and control with lots of useful features.  Trolling motors are offered for both freshwater and saltwater fishing and can be mounted in 1 of 3 locations: on the engine itself, on the transom (stern), or on the bow. Following are guidelines on how to mount a trolling motor in each of these positions.












9.1) installing the trolling motor on Transom

            Mostly trolling motors are used to cover short distances and are often installed on transoms. This makes controlling the boat from back easier.







1)    Transom trolling motors have 1 or 2 clamps that are manufactured into the mounting bracket to hold the motor in firmly place. Turning the clamps counterclockwise (to the left) will open them while turning them clockwise will tighten them. You need to tighten up the clamp screws properly to avoid any accident.

2)    Fix the trolling motor over the transom. It should be placed in the center of the stern but must not disturb the functioning of the engine.  The top of the mounting bracket must be fixed with the top of the stern.  

3)    Tighten the clamps appropriately.


You need to position transom trolling motor the way that its center must sink at least upto 9 inches under the water to keep the propeller away from breaking the surface of the water which creates noise.

9.2) installing the trolling motor on Bow

Pulling boat is more efficient than pushing it into the water. Fixing trolling machine on bow offers more control to operate the motor. Bow trolling machines are more expensive but they have many features as compared to others such as more steering control, controlling motor with wireless remote control, foot pedal and better view of water ahead.



1)    Choose an appropriate location on the deck of the boat to place the trolling motor but make sure the mounting screws must not pierce the hull. These are used with the boats that are flat and raised forward.  

2)    Decide and mark the holes you need to drill into the deck to fix the motor. Use bow mount base as a template to mark the location of the front mounting holes in the plastic deck and the rear mounting holes on the mount base.

3)    Using a head screwdriver and the deck screws, lock the deck to the mount base. (The deck for heavy duty spring mounts can be installed at the end.)

4)    Drill the holes up to 6.5 mm but if you are utilizing rubber mounting isolators then drill each mounting hole 13 mm (0.5 in.) diameter and then clear all the debris.

5)    Slide a rubber washer onto each bolt, under the mount base.

6)    Now carefully position the base over the drilled holes and slip each of the bolts through the hole.

7)    Make sure that the base has a rest level against the deck surface. If it has not then you'll need to add more rubber washers under those bolts where the base vibrates to level it. The base needs to rest consistently so that the motor can be lifted onto the deck and locked down for move without binding.

8)    Strand a steel washer and retaining nut onto every bolt. Tighten the nuts to lock the base.


Bow mount trolling motors should run at least 5 inches (12.5 cm) underneath the water level in uneven water.


9.3) Installing a Trolling Motor on the Engine

Engine mount trolling motors present great space-saving reimbursements but are also a bit more confusing than traditional bow mount motors. While buying Engine trolling motors make sure they are compatible with your boat. Here, we'll discuss how to install it to your outboard motor.  




The procedure of Engine trolling motor’s installation is straight forward and pretty simple that is briefly explained below:

1)    Rest the mounting bracket on peak of the engine's anti-cavitation plate, while keeping the motor up. Try to site it as close to the outboard as possible also slide it back if needed.  The mounting bracket / legs for the engine mount motor may need to be bent moderately in order to accommodate the outboard motors back. Remember your anti-cavitations plate must run at a deepness of at least 13 inches underneath the water, so that the trolling motor will run at least 6 inches underneath the water when in operation.


2)    While holding the motor in place, drill six holes following the pattern of holes on the anti-cavitation plate.

3)    Place the insulator between the cavitation plate and the engine-mounted motor.

4)    Insert the six bolts carefully and fasten them.

5)    Thread the cable via the cable hooks and into the boat.  Make sure to leave the cable enough loose to allow for lifting and lowering of the primary outboard engine.  

6)    When firming up the wiring, make sure to use the provided glued heat shrink to reduce the chance of deterioration
