Evinrude E90DGX Outboard Motor

This used Evinrude E90DGX is a three-cylinder outboard built on a 25-inch shaft, the longer-leg option for boats with a taller transom.

Engine and rigging

Displacement works out to 79 cubic inches, the primary gear ratio is 2.25:1, and this motor climbs toward a 5,000-5,500 rpm ceiling at full throttle. Steering runs remote with a tiller accessory available as an add-on, and a Trac-1 system covers trim adjustments rather than a manual lever at the stern.

Weight and finish

At 335 lbs, this is one of the heavier units in this three-cylinder family, a difference that comes with carrying the longer leg. Controls are graphite-finish, and starting is electric rather than by rope, with power trim and tilt handled automatically from the console rather than by hand.

Why shaft length matters here

Boats with a taller transom need the extra reach of a 25-inch shaft to keep the propeller properly submerged, so matching this dimension to your hull matters more than matching the control color.

Who picks the long-shaft version

Pontoons, houseboats, and some larger center consoles sit their transom higher off the water than a typical runabout, which is exactly the situation a 25-inch shaft is meant to address on this three-cylinder engine.

What shaft length is this? 25 inches.

How much does it weigh? 335 lbs.
