Mercury 115ELPT Command Thrust FourStroke

This used Mercury 115ELPT Command Thrust FourStroke runs a 20-inch shaft with remote steering, the shorter-shaft sibling in this fleet to the extra-long Command Thrust versions, for boats with a standard transom that still want Command Thrust's bigger propeller bite.

Shaft length and gearcase to confirm

At 20 inches, this shaft suits a mid-length transom rather than the taller transoms the extra-long versions in this lineup are built for; measure before ordering. This engine's own gearcase field also reads standard rather than the Command Thrust housing implied by the model name, so confirm the exact gearcase with us if matching propeller pitch and diameter to a true Command Thrust spec matters for your boat, especially if you are replacing a worn prop rather than buying a spare.

Specifications

Full throttle sits at 5000-5800 rpm with a 2.07:1 ratio, a CARB star rating of 3, and a dry weight of 363 pounds. Power comes from an inline four with a single overhead cam, 8 valves, and multi-port electronic fuel injection, started with Smart Start electric ignition and watched over by SmartCraft Engine Guardian. Propeller is not included; it comes finished in Phantom Black.

What shaft length is this engine? 20 inches, for a mid-length transom. Is a propeller included? No, it ships without one. Does the Command Thrust name still matter if the gearcase is standard? It is still useful shorthand for the model line, but confirm the gearcase itself with us if propeller fitment depends on it.
