Nissan 2015 Nissan 20 Hp NSF20CEF2 Outboard Motor

This 20 HP Nissan reaches a bit deeper than its short-shaft sibling, built on a 20-inch shaft for boats with a taller transom, while keeping the same tiller steering and push-button electric start. Coverage runs under Nissan's 5-year warranty, a longer term than many portable outboards carry. Who this motor suits Larger jon boats, fishing skiffs, and small commercial hulls built around a 20-inch transom are the target here; mount the wrong shaft length and the propeller ends up running too deep or too shallow, which affects handling more than raw power. The twin-cylinder engine is fed by a carburetor and cooled through a thermostat-controlled water circuit, with digital CD ignition timing each spark, and turns a 3-blade aluminum prop measuring 9.2 inches across with 9.1 inches of pitch through a front-mounted shifter. Setup notes Electric start is powered by a 145-watt alternator fitted as standard equipment, so no extra charging hardware is needed on this one. Trim and tilt remain manual rather than power-assisted, and fuel is held in a tank outside the motor, rated at 3.1 gallons and joined by its own hose, with the propeller, a printed manual, and a tool kit rounding out what arrives in the crate. Boaters who already run a short-shaft Nissan of this size will find the controls and starting sequence identical, just with more reach below the transom. Common questions What changes between this and the short-shaft version? Mainly the shaft length and the propeller's pitch; the engine and controls carry over unchanged. Is saltwater use covered? Yes, this engine carries a saltwater rating.
