Minn Kota | Riptide SF Bow Mount Trolling Motor | Saltwater | 24V | 80 lb Thrust | 52" Shaft | 1363640

Product Overview

The Minn Kota | Riptide SF Bow Mount Trolling Motor | Saltwater | 24V | 80 lb Thrust | 52" Shaft | 1363640 is a rugged, ultra-reliable mechanical bow-mount trolling motor engineered specifically to deliver no-nonsense power and stealth operation in harsh saltwater environments. Carrying the "SF" designation for Saltwater Fortrex configuration, this motor features an innovative **Mono-Arm Mount Design** that redefines marine durability. Machined from a single extruded, structural-grade anodized aluminum beam, the Mono-Arm operates with a single hinge point and a rear pivot bearing that provides 20% more surface area than traditional brackets. This structural focus results in an incredible 75% reduction in mount torsion and completely eliminates metal-on-metal contact, ensuring that the motor operates with absolute silence and zero mechanical play when accelerating or carving along shallow coastal flats.

Operating on a clean 24-volt DC electrical architecture, this motor pushes out a dependable 80 pounds of continuous thrust, providing the ideal power-to-weight ratio to maneuver mid-sized bay boats, flats skiffs, and aluminum coastal craft through heavy winds and coastal tides. To take the physical strain out of manual motor handling, the Riptide SF features an integrated **Lift-Assist** system. Outfitted with a nitrogen-charged, stainless steel gas spring, the lift assist cuts the physical weight of stowing and deploying the motor in half, making it as easy as lifting an SUV tailgate. Control is driven by an ergonomic, hand-steer **Tilt/Extend Tiller** handle that can tilt up to 45 degrees and telescope outward an additional 6 inches to accommodate standing or seated casting positions. The system comes complete with a built-in Counter-Tension Stabilizer spring, a Quick-Lock cam depth adjuster, a push-to-test battery gauge, an encapsulated Digital Maximizer control board, a zinc sacrificial anode, and a weedless Weedless Wedge 2 propeller (MKP-33).

Key Features

• Thrust Capacity: 80 lbs (24V)
• Shaft Length: 52"
• Revolutionary Mono-Arm Mount: Constructed from a single piece of extruded, anodized structural aluminum that operates with 75% less torsion and zero metal-on-metal contact for silent, long-lasting durability.
• Nitrogen-Charged Lift-Assist: Integrated stainless steel, nitrogen-charged gas spring cuts the physical weight of stowing and deploying the motor in half, allowing for effortless deck operation.
• Tilt/Extend Ergonomic Tiller: Premium hand-steer handle extends up to 6 inches and tilts up to 45 degrees upward, providing optimal comfort and immediate control from any casting position.
• Counter-Tension Stabilizer (CTS): Utilizes an integrated spring mechanism that applies continuous counter-force whether stowed or deployed, eliminating play, wobble, and steering torque.
• Advanced Saltwater Armor Plating: Marine alloys undergo a multi-step cleaning and zinc dichromate armor plating process before being sealed under a 5-mil TGIC polyester powder coat paint finish.
• Fully Encapsulated Electronics: Internal control boards are completely sealed in high-grade marine urethane, and all wire joints utilize liquid-tight heat shrink tubing to form an impenetrable barrier against salt air.
• Digital Maximizer Power Savings: Regulates current draw dynamically to deliver only as much power as needed, reducing destructive heat and extending battery lifespan up to 5 times on a single charge.

Compatibility Information

The Minn Kota Riptide SF 80lb 52" trolling motor (part number 1363640) is optimized exclusively for bow-mount installations on saltwater and brackish vessels. Its versatile 52-inch shaft length is universally compatible with standard mid-sized saltwater craft, including flats skiffs, bay boats, aluminum coastal fishing rigs, and technical shallow-water skiffs where the deck-to-waterline distance does not exceed 22 inches, keeping the lower unit perfectly submerged.

Electrically, this motor runs strictly on a 24-volt DC configuration and requires two high-quality 12V marine deep-cycle batteries (flooded lead-acid, AGM, or lithium) wired together in a series loop. To safeguard the fully encapsulated internal circuitry from overcurrent spikes, the installation must be fitted with a manual-reset 50-amp circuit breaker on the positive power line. This motor interfaces cleanly with Minn Kota's premium quick-release mounting brackets, such as the RTA-19 plate.

Frequently Asked Questions

How does the Bowguard 360 breakaway system protect my boat deck if I strike a rock?

The Riptide SF features a patented Bowguard 360° breakaway bracket housing. If you are tracking along a shallow flat or mangrove shoreline and your lower unit violently strikes a submerged rock, oyster bar, or log, the bowguard mechanism allows the shaft to break away from its vertical lock from any angle of impact. This automatic pivot absorbs the destructive energy of the strike, preventing the shaft from snapping and protecting your boat's fiberglass deck from cracking. Once you clear the obstruction, the bowguard automatically spring-resets back into its vertical operational slot, allowing you to keep fishing without tools.

What is the purpose of the zinc sacrificial anode mounted on the lower unit propeller hub?

The sacrificial zinc anode serves as a vital electrical shielding shield against galvanic corrosion. Galvanic corrosion occurs naturally when different metallic alloys are submerged together in highly conductive saltwater. Saltwater will automatically target and attack the weakest metal first. By placing a pure zinc anode on the lower unit propeller hub, the saltwater will corrode the zinc piece completely while leaving your expensive aluminum lower unit torpedo housing, steel prop shaft, and motor brushes completely untouched. You should inspect this anode annually and replace it once it has degraded by half.

Can I adjust the tightness or tension of the steering handle if it rotates too freely?

Yes, the steering tension on the hand-control Riptide SF is completely adjustable to fit your exact operational preference. If you prefer a loose, fast-turning handle, or if you want to tighten the friction so the motor holds its directional track when you let go of the tiller, you can adjust the steering tension collar knob located directly on the main pivot bracket beneath the head. Turning this ergonomic collar clockwise increases friction on the composite shaft sleeve, reducing steering torque feedback and locking your angle in place, while a counterclockwise turn loosens the swing.

What wire gauge size should be used to extend the battery wires to the front bow deck?

Because an 80-pound thrust motor draws up to 56 amps at maximum speed, using heavy-gauge marine wire is critical to avoid voltage drops and dangerous overheating along the line. If your deep-cycle batteries are located within 15 feet of your bow trolling motor plug, standard 8 AWG marine-grade copper wire is fully sufficient. However, if your batteries are stored back in the stern transom compartment and the wire run measures between 15 and 25 feet in length, you must upgrade to thicker 6 AWG wire to ensure the motor receives full voltage and runs cool.

Can the 52-inch shaft length be shortened if I am fishing in ultra-shallow backcountry flats?

Yes, you can easily adjust the running depth of your lower unit to float over shallow sand flats or oyster reefs using the integrated Quick-Lock cam depth adjuster located directly on the aluminum mount framework. To raise the motor, simply flip open the quick-cam lever, slide the composite shaft upward through the mount sleeve until the propeller lower unit sits just below the surface hull line, and clamp the cam lever tightly shut. This secure lock prevents the motor from slipping downward, allowing you to execute silent shallow water maneuvers without dragging bottom.
