2019 Yamaha 20 HP F20LMHB Outboard Motor

The 2019 Yamaha F20LMHB starts by pull cord alone: 20 hp, two cylinders, a 20-inch shaft, and tiller steering, with no electric backup involved. New, it weighs 130 lbs, fuel-injected at 432cc, with a full-throttle range of 5000 to 6000 rpm.

What manual start and EFI together mean

This version skips the starter motor and battery entirely, so there is less weight and less wiring to maintain than an electric-start version of this same engine, while EFI still gives steadier cold starting and running than a carburetor would at this size. The tradeoff is pulling a starter cord instead of pressing a button, and no electric backup if the cord ever fails.

Fit before you buy

Shaft length on this engine is fixed at 20 inches from the factory; there is no trim adjustment that compensates for a transom built for a different length, so measure first.

Running a fuel-injected tiller motor

EFI on a motor this size mostly shows up as easier starting in cold weather and a smoother idle than a carbureted engine tends to give, without adding the weight or complexity of a battery and starter motor.

Common questions

Is there an electric start option? Not on this version; starting is manual pull-start only. Carbureted or fuel-injected? Fuel-injected. How much does this one weigh? 130 lbs, with a 3-year warranty included.
