Mercury 9.9EL FourStroke Outboard Motor

This used 9.9EL FourStroke runs a 20-inch shaft with electric start and remote rather than tiller steering, and unlike some siblings in the catalog, this particular listing carries no Command Thrust name stamped on its gearcase.

Set up for console steering

Remote steering means the helm needs its own throttle and steering controls, sold separately from this motor; there's no tiller arm here at all, so plan the rigging before you buy. The shaft length matches a standard transom height rather than a shallow or deep-set one.

Mechanically

Expect a carbureted engine with CDI ignition and electronic spark advance, a 2.08:1 gearcase ratio, and manual ratcheting trim rather than a powered tilt system, all at a modest dry weight for this size class of outboard.

Buying used

Ask the seller about run hours and recent service before relying on the spec sheet alone, since wear varies motor to motor on used outboards far more than on anything sold new from the factory floor. Octane needs top out at 87, with ethanol blends up to 10 percent tolerated without issue, and the recommended oil is Mercury's own FourStroke 10W-30.

Common questions

Is steering included? No, remote steering controls are sold separately.

What's the finish color? Phantom Black.

What's the gear ratio on this one? 2.08:1, the standard Mercury gearcase for this size motor.
