2023 Mercury Marine® FourStroke 90 hp

2023 Mercury Marine® FourStroke 90 hp – Unmatched Torque & Lightweight Efficiency

Upgrade your vessel with the 2023 Mercury Marine® FourStroke 90 hp, a class-leading outboard engine designed to deliver heavier torque in a lighter package. Ideal for repowering bass boats, aluminum consoles, and runabouts, this motor offers the perfect blend of acceleration, fuel economy, and reliability.

Engineered to Perform

The secret to the Mercury 90 hp FourStroke’s success lies in its displacement. Boasting a massive 2.1-liter powerhead, this engine works smarter, not harder. By generating abundant torque at lower RPMs, the engine delivers exceptional hole shots and acceleration, getting your boat on plane faster than the competition. Because the engine isn't constantly stressed to reach performance metrics, you enjoy a smoother, quieter ride and extended engine life.

Lightweight Architecture, Heavyweight Results

Despite its high displacement, the 2023 FourStroke 90 hp features an advanced, lightweight design. By trimming unnecessary weight, Mercury has created an engine that improves your boat’s overall handling and fuel efficiency. Whether you are navigating shallow fishing spots or cruising open water, the reduced weight on the transom translates to better draft and more responsive steering.

Versatile Application & Easy Ownership

This outboard is the ultimate "do-it-all" engine. It is specifically calibrated to serve a wide variety of hulls, including deck boats, inshore fishing vessels, aluminum tillers, inflatable rigid hulls, and fish & ski setups. Beyond performance, Mercury has prioritized the ownership experience. The maintenance-free valve train eliminates the need for costly valve clearance adjustments, and the color-coded maintenance touchpoints make routine checks intuitive and fast.
