Common Question of Mercury 115ELPT EFI
Is the 115ELPT EFI fuel injected?
Yes. The EFI designation identifies an electronic fuel injection system on this Mercury 115-horsepower outboard. Its 20-inch shaft suits a matching transom, while fuel injection supports controlled delivery during starting, acceleration, and cruising. Confirm controls, battery, wiring, steering, and hull rating before installing this high performance outboard motor.
What transom fits its shaft?
A 20-inch transom is the intended match for this EFI model. Measure the boat according to the manufacturer’s procedure before mounting. Correct shaft length supports cooling-water pickup, gearcase position, propeller immersion, steering response, and efficient trim. Accurate measurement supports this ready to bolt marine installation.
What should buyers verify?
Verify the boat’s maximum horsepower, transom strength, engine weight capacity, steering hardware, remote controls, battery requirements, wiring, fuel supply, gauges, and package contents. EFI components must be compatible with the boat’s electrical system. Follow Mercury installation and service documentation before repowering or operating the outboard.
