Details & Inspection Notes

Mercury built this 2018 9.9EH (SKU 9.9EH-18) to stay light and compact: a twin-cylinder, 9.9 HP four-stroke on the short shaft, with electric starting and tiller control.

Designed to be portable

That portability suits small pontoons, skiffs, and jon boats as a primary motor, or sailboats and trolling setups relying on it as auxiliary power. Auto-ratchet hardware handles tilt adjustment at the tiller, which also combines shifting, throttle, and steering in one grip.

Specifications to confirm

Charging runs through a 76-watt alternator on this electric-start build. Gearcase ratio sits at 2.08:1. Mercury covers it for saltwater use, with the standard factory term protecting three years of ownership. A snug-fitting cover reduces cowl fading on a motor stored outside between outings.

Q: Does this motor include an internal battery? No, there is no internal battery with this model.

Q: What size boats is this meant for? Small pontoons, skiffs, and jon boats, either as primary power or auxiliary backup.

Q: Does the tiller combine throttle and steering? Yes, one tiller handle covers shifting, throttle, and steering together on this build.

Q: Does this one carry a saltwater rating? Yes, saltwater running is covered under Mercury's rating for this motor.

Q: Is there a backup way to start it? Yes, a thru-cowl manual option backs up the electric starter here.
