2017 Mercury 9.9 HP 9.9EH Outboard Motor

This 2017 Mercury 9.9EH (SKU 9.9EH-17) runs 9.9 HP across two cylinders on the short shaft, meant as a second motor rather than the main one, with electric starting and tiller steering. Use case for this size Small pontoons, skiffs, and jon boats take this short-shaft 9.9 as their main power, while it also serves as sailboat auxiliary or trolling muscle paired with a bigger engine. Mercury's auto-ratchet system manages tilt by hand, and the multi-function tiller handle covers shifting, throttle, and steering together. Engine details A manual backup lives in the cowl beside the electric starter, which runs off a 76-watt alternator. Gearcase ratio here is 2.08:1. Saltwater use is fine under Mercury's rating, and ownership is protected by the standard three-year term. A spare prop nut and washer are worth keeping aboard in case one works loose. Q: Is saltwater use okay with this one? Yes, it carries Mercury's saltwater rating. Q: Does it start by button or by cord? Electric, by push-button, with a manual backup built into the cowl. Q: Is this motor meant to be a main engine? It can be, though it's commonly run as a backup alongside a larger one. Q: Is power trim fitted on this unit? No, tilt adjusts by hand through Mercury's auto-ratchet system. Compare it with other Mercury outboards near this horsepower.
