Details & Inspection Notes
Tiller-steered, electric-started, and built on the short shaft, this 2017 Mercury 8EH (SKU 8EH-17) runs an 8 HP twin-cylinder four-stroke suited to small utility hulls.
One grip, several controls
Mercury's multi-function tiller handle puts shifting, throttle, throttle tension, steering, and the engine stop switch under a single hand, which helps on a small boat where both hands are rarely available. Tilt and trim angle adjust through the patented auto-ratchet hardware without needing extra tools, and the gear lever runs forward, neutral, and reverse.
Specifications worth checking
Top speed on this twin reaches 6,000 rpm. The carburetor pulls fuel from an external tank. A 6-amp alternator backs the electric starter, with a pull-cord option in the cowl as insurance. Mercury's coverage on this unit is the standard three-year factory term. A clean carburetor jet makes the biggest difference in cold starting on a small twin like this.
Q: Is there a backup way to start it if the battery is low? Yes, a manual start through the cowl backs up the electric starter.
Q: Will this motor work on a skiff or jon boat? Yes, the short shaft and compact size fit both well.
Q: Does it tilt up for shallow water? Yes, the tiller-mounted controls include tilt adjustment for running shallow.
