T-H Marine Troll-Tamer Trolling Motor Stabilizer Lock for Minn Kota Fortrex 2.75″-4.5″

The T-H Marine Troll-Tamer Trolling Motor Stabilizer Lock for Minn Kota Fortrex 2.75″-4.5″ is a rugged support system designed to securely hold a stowed trolling motor and reduce damaging bounce while the boat is underway. The correct model for this configuration is RMC-105FMK-DP, with UPC 733572078558. Current retailer listings describe the spacing as 2-3/4″ to 4-1/2″, while T-H Marine’s current compatibility chart lists the nominal range as 2-3/4″ to 4-1/4″; measuring the actual installation before purchase is therefore important.

Secure Support for Minn Kota Fortrex

The T-H Marine Troll-Tamer for Minn Kota Fortrex provides an additional support and locking point for the trolling motor while it is in the stowed position.

A trolling motor mounted at the bow can experience repeated vertical movement when a boat crosses waves or wakes. T-H Marine designed the Troll-Tamer to securely hold the motor in position and help reduce stresses that can affect the trolling motor, mount and boat during travel. (Hardin Marine)

For anglers who frequently travel across rough water, this provides a substantial mechanical support system rather than relying solely on the trolling motor’s primary mount.

Heavy-Duty 300 Series Stainless Steel

Durability is one of the main features of the RMC-105FMK-DP.

T-H Marine manufactures the Troll-Tamer from 300 Series stainless steel, providing strength and corrosion resistance for marine environments. The stainless construction is designed to withstand repeated use and demanding conditions. (Hardin Marine)

This construction also helps make the stabilizer suitable for heavier bow-mounted trolling motors where controlling movement during transport is especially important.

2.75″-4.5″ Spacing

This version is commonly sold as the 2-3/4″–4-1/2″ Fortrex Troll-Tamer, and multiple current product listings use that range. (BassFishin Electronics, LLC)

However, T-H Marine’s current official compatibility guide lists RMC-105FMK-DP at 2-3/4″–4-1/4″ for Minn Kota Fortrex and Ultrex, Garmin Force and Lowrance Ghost. (T-H Marine Supplies)

For an accurate product listing, you can retain 2.75″-4.5″ in the product title if that matches the manufacturer/distributor title supplied with your inventory, while noting the current compatibility chart in the specifications.

How to Measure for the Correct Troll-Tamer

T-H Marine says the key measurement is the spacing between the bottom of the trolling motor mount and the boat deck at the location where the Troll-Tamer will be installed. (T-H Marine Supplies)

That measurement determines which FMK model is appropriate:

The same current chart lists these three ranges for both Minn Kota Fortrex and Ultrex applications. (T-H Marine Supplies)

Locking Pin and Quick-Release Base

The Troll-Tamer isn’t simply a support post. It incorporates a locking pin and quick-release toe-kick base.

The locking mechanism secures the trolling motor when stowed, while the quick-release system allows the motor to be released before deployment. (Hardin Marine)

This provides additional support during travel without preventing normal trolling-motor operation once the stabilizer has been released.

Helps Reduce Trolling Motor Bounce

The primary purpose of the T-H Marine Troll-Tamer RMC-105FMK-DP is to reduce unwanted trolling-motor movement during transport and operation in rough conditions.

By providing another rigid support point, the Troll-Tamer helps prevent the stowed motor from repeatedly bouncing against its primary mounting system. T-H Marine describes the product as designed to help prevent damage to both the trolling motor and boat. (Hardin Marine)

Compatible Beyond Minn Kota Fortrex

Although this product is commonly marketed as the Minn Kota Fortrex Troll-Tamer, T-H Marine’s current compatibility chart also lists RMC-105FMK-DP for several other motors when the mounting measurement is correct.

These include Minn Kota Ultrex, Lowrance Ghost and Garmin Force installations within the manufacturer’s specified range. (T-H Marine Supplies)

Compatibility should therefore be determined by both trolling-motor model and actual motor-to-deck measurement.

RMC-105FMK-DP vs. RMC-104FMK-DP

These models are easy to confuse.

RMC-105FMK-DP is the shorter Fortrex/Ultrex configuration, officially listed at 2-3/4″–4-1/4″ in T-H Marine’s current chart.

RMC-104FMK-DP covers 3-1/2″–5″, making it suitable when the installation requires additional height. (T-H Marine Supplies)

Because the ranges overlap, taking an accurate measurement before ordering is more reliable than selecting solely by trolling-motor model.

Installation and Use

Before installation, fully stow the trolling motor and measure the motor-to-deck distance at the intended mounting point. Verify that the measurement and trolling-motor model match T-H Marine’s compatibility information.

Install the stabilizer according to the manufacturer’s supplied instructions so it supports the motor without interfering with steering, deployment or other moving components.

Before deploying the trolling motor, release the stabilizer and verify that the trolling motor can operate normally.
