Minn Kota Riptide Instinct QUEST 90/115 Trolling Motor – 87" Shaft – White

Built for the most demanding offshore and coastal environments, the Minn Kota Riptide Instinct QUEST 90/115 with 87-inch shaft is the definitive trolling motor for serious anglers running large center consoles, walkarounds, and sportfishing vessels. The Instinct combines fully automatic stow and deploy, Power Trim, GPS-guided navigation, and the powerful brushless QUEST drive system into one premium offshore-ready package.

At this shaft length, the Instinct's Auto Stow & Deploy isn't just a convenience feature — it's a practical necessity. Manually lifting and stowing a motor of this size is impractical and potentially unsafe on a large vessel. With the push of a button via the included wireless remote, the One-Boat Network app, or a compatible Humminbird fish finder, the motor deploys, trims, and stows automatically.

Built for Big Water

The 87-inch shaft was designed for anglers who regularly fish in conditions where wind, swell, and current can lift the bow significantly. The extra shaft length helps maintain reliable propulsion and GPS anchoring performance when shorter shafts may lose effectiveness — keeping Spot-Lock engaged, steering responsive, and thrust consistent even when conditions turn challenging.

Why Choose the 87" Shaft?

The 87-inch shaft is designed for larger offshore and high-freeboard boats where maintaining propeller depth is critical. In rough seas, large swells, or strong tidal current, shorter shafts can allow the propeller to ventilate as the bow rises. The additional shaft length helps keep the prop engaged, providing more consistent thrust, steering control, and Spot-Lock performance when conditions become challenging.

Anglers running large center consoles in the Gulf of Mexico, along the Atlantic coast, or targeting salmon and trout in the Great Lakes open-water fisheries will find the 87" provides the depth and stability needed to fish confidently in demanding conditions. If your boat has a high bow profile or you regularly fish in open, exposed water, the 87" is the right choice.

• Tournament anglers requiring maximum reliability in demanding conditions

Standout Features

Auto Stow & Deploy

Deploy or retrieve the trolling motor with a single button press. On a large offshore vessel, this is a critical safety and ergonomics feature — eliminating the heavy lifting that makes manual motors impractical at this shaft length.

Power Trim

Raise or lower the motor while fishing without leaving the helm. On larger vessels in offshore conditions, the ability to quickly adjust motor depth without manual intervention is a significant operational advantage.

QUEST Brushless Technology

The QUEST platform features a brushless motor with a reinforced mount and stronger steering system, delivering improved efficiency, longer runtime, reduced maintenance, and quieter operation — all critical on extended offshore trips where battery runtime and reliability matter most.

Spot-Lock with Jog

Hold your boat within feet of your chosen location using GPS anchoring, then make precise position adjustments using the Jog feature. Invaluable when holding position over offshore wrecks, reef edges, or structure in current.

Drift Mode

Maintain a controlled drift speed and direction while compensating for wind and current. Particularly effective when drifting live bait over offshore wrecks or working deep reef edges.

Follow Mode

When paired with a compatible Humminbird fish finder, the motor automatically follows selected depth contours, vegetation edges, or bottom hardness — keeping you in the strike zone on complex offshore structure without constant steering input.

Frequently Asked Questions

Is an 87-inch shaft too long?

Not necessarily. An 87-inch shaft is recommended for larger boats with higher bows or for anglers who frequently fish in rough offshore conditions. Choosing the correct shaft length helps keep the propeller submerged, improving steering, thrust, and Spot-Lock performance. Minn Kota offers the Instinct QUEST in 60", 72", 87", and 100" lengths so anglers can match the motor to their boat and fishing conditions.

Why choose the 87-inch shaft over the 72-inch version?

The 87-inch shaft is designed for large offshore vessels with high bow profiles where the 72" would leave the prop too close to the surface in rough conditions. At 87 inches, the propeller maintains consistent depth in offshore chop, providing reliable thrust and steering authority in demanding open-water environments.

Does the Instinct automatically deploy and stow?

Yes. The Riptide Instinct features fully automatic stow and deploy functionality controlled via the included wireless remote, compatible Humminbird units, or the One-Boat Network app.

Can I run this on either 24V or 36V?

Yes. The dual-voltage QUEST platform operates on either a 24-volt or 36-volt battery system, delivering up to 90 lbs of thrust on 24V and up to 115 lbs on 36V. For large offshore vessels, we recommend 36V for maximum thrust and runtime.

Is this compatible with Humminbird fish finders?

Yes. It integrates with compatible Humminbird units through the One-Boat Network, enabling Follow Mode, route management, and advanced navigation features.
