2017 Yamaha F20 LEA Outboard Motor

Twenty horsepower from a 362cc two-cylinder SOHC block drives this F20 LEA, mounted on a 20-inch shaft, with manual or electric starting and a dry weight of 117 lbs.

Shared engineering across the F20 line

Bolt pattern for the transom mount spaces out at 28.6 inches, drive reduces through a 2.08:1 gear set across forward, neutral and reverse, compression is rated 9.3:1, and the four-stop tilt bracket runs from 67 up to 71 degrees. Steering swings up to 45 degrees from center each direction, while fuel comes through a single carburetor working together with CDI microcomputer ignition.

One detail worth flagging: the warranty terms listed for this engine carve out a shorter period specifically for a jet pump assembly, which suggests a jet lower unit exists somewhere in this engine family; confirm the exact configuration of this particular unit with us before ordering.

Buyers moving up from a smaller portable to this 20 hp block often notice the extra displacement on plane with a loaded boat, even though the shaft and mounting hardware carry over largely unchanged from lighter engines in the same family.
