Evinrude E90GNL 90HP Outboard Motor

This used Evinrude E90GNL is a 90-hp, three-cylinder outboard tuned specifically for pontoon boats, running mechanical controls and remote steering.

Pontoon-specific tuning

Evinrude built this motor's gear ratio and throttle mapping around pontoon use, aiming for quicker acceleration and more stopping power with a pontoon loaded down with passengers, which sets it apart from a standard-mount outboard of similar output rigged for a different hull shape.

Engine and rigging

Displacement is 79 cubic inches, the primary gearing is set at 2.36:1, and this motor runs toward 5,000-5,500 rpm wide open. A Trac-1 unit covers trim adjustments, and the package weighs 320 lbs on a 20-inch shaft.

Matching motor to hull

A pontoon-tuned motor like this generally isn't the right choice for a deep-vee runabout, since its gear ratio and software mapping are built around a flatter, heavier hull running at modest speed rather than chasing top-end numbers on open water.

Checking fit before ordering

Measure the 20-inch shaft against your pontoon's existing mounting bracket, and confirm the mechanical control setup matches whatever shift and throttle hardware is already installed at the helm before placing an order.

Is this tuned for a specific boat type? Yes, gear ratio and throttle mapping are set up for pontoons.

Are the controls mechanical or digital? Mechanical, not a digital throttle.
