2015 Nissan 6 Hp NSF6C4 Outboard Motor

The NSF6C4 stretches to a 25-inch shaft, the longest in Nissan's 6 HP line, and swaps the standard propeller for a high-thrust design, aimed squarely at boats with an unusually tall transom or heavier hulls that need more push than speed.

What sets this one apart

That high-thrust propeller, an 8.375-inch, 3-blade design, is unique to this extra-long-shaft model; the shorter shaft lengths in this family use a different, smaller prop better suited to lighter loads. This is also the one 6 HP variant where the charging alternator comes installed from the factory rather than sold as an add-on kit, so it's ready to keep a battery topped off without extra parts.

Engine basics

A single cylinder runs through a carburetor and OHV valves, with cooling handled by a thermostat-controlled water jacket and a saltwater rating covering the whole unit. A tank sized at 3.1 gallons sits outside the motor, joined by its own quick-connect hose, and starting is strictly by manual pull cord. A manual and tool kit accompany the motor, backed by Nissan's 5-year warranty. For a boat that gets beached often or towed on a trailer, the extra reach of this shaft length can matter more than the horsepower number itself.

Common questions

Why a different propeller on this model? The extra-long shaft pairs with a high-thrust prop built for pushing heavier or slower boats.

Does charging equipment come standard here? Yes, this is the only 6 HP variant with the alternator pre-installed.
