2015 Nissan 8 Hp NSF8A31 Outboard Motor

The Nissan NSF8A31 steps up from the 6 HP class to 8 HP, keeping a short, 15-inch shaft, tiller steering, and a manual pull cord, still light enough for one person to manage without a battery on board.

What to check before buying

Confirm this short shaft suits your transom before ordering, since Nissan also builds this same 8 HP block for taller boats. Two cylinders run through SOHC valves and a carburetor, cooled by a thermostat-regulated water jacket, with the whole unit cleared for saltwater use and geared at 2.08 to 1 through a front-mounted shift lever that turns a standard, 3-blade aluminum propeller sized for this horsepower class.

Fuel, charging, and extras

A 3.1-gallon tank mounted outside the motor supplies fuel through its own hose. Since this is the pull-start version, a charging alternator is offered as a separate, optionally installed kit rather than built in. A manual and tool kit come packed with the motor, and Nissan covers it with a 5-year warranty. This model tends to suit boaters moving up from a 6 HP motor who want noticeably more push without jumping to electric start.

Common questions

Does this version start electrically? No, this one uses a pull cord; an electric-start 8 HP is also available.

Can charging equipment be fitted later? Yes, as a separately installed option.

Nissan's outboards in this class share their engineering with the equivalent Tohatsu model, the two brands differing mainly in badge and finish.
