Yamaha F20LWHB 20HP Outboard – 20in Shaft, Electric, Tiller

Description

Freezing early morning duck hunts become infinitely more comfortable with the push-button ignition of the Yamaha F20LWHB. Drawing from a massive 432cc displacement, this twin-cylinder EFI block forces aggressive low-end torque, pushing heavily loaded aluminum jon boats upstream against strong river currents. Verifying your exact transom height guarantees this electric start long shaft outboard places the water intakes deep enough for safe operation.

Clear submerged rocky obstacles safely in shallow creeks by utilizing the manual tilt bracket as a direct physical lifting aid. You grab the rear cowl grip to pull the 62 kg gearcase upward instantly to prevent devastating impacts. Yamaha engineers the lower unit using impact-deflecting marine aluminum. This structural barrier stops galvanic decay completely when repowering tall transom utility boats in harsh brackish environments.

Key Features of Yamaha F20LWHB

• Turn-Key Electric Start: Engages the flywheel instantly via 12-volt battery power, eliminating physical pull strain completely during freezing early morning launches.
• Battery-Less EFI Backup: Atomizes fuel perfectly using internal magnetic power, guaranteeing reliable pull starts if your primary starting battery fails offshore.
• 20-Inch Long Shaft: Places the anti-ventilation plate deeply beneath tall utility transoms, preventing water pump starvation in heavy chop.
• Multi-Function Tiller Handle: Concentrates shift and throttle inputs squarely in your grip, sharpening handling response in narrow twisting creeks.
• 16-Amp Charging Alternator: Outputs constant electrical current while running, keeping small deep cycle batteries topped off for demanding marine electronics.
• 432cc Inline-Two Block: Produces massive low-end torque internally, lifting heavily loaded 16-foot work boats onto plane much faster.
• Manual Tilt Bracket: Features a rigid mechanical lock, safely holding the gearcase out of the water physically while moored at the dock.
• 2.08:1 Gear Ratio: Multiplies engine torque effectively, translating the 432cc displacement into relentless pushing force for heavily loaded skiffs.
• Through-Prop Exhaust: Channels toxic combustion gases directly underwater, keeping the aft operator station completely free of smoke.
• Clean Four-Stroke Combustion: Burns unleaded fuel highly efficiently without messy two-stroke oil mixing, keeping pristine anchorages completely free of surface oil slicks.

Why Choose Yamaha F20LWHB

This specific build fits only 20-inch transoms requiring direct physical tiller control alongside electric start capabilities. The extended shaft creates massive drag if mounted on a standard 15-inch boat. You cannot wire this to a forward console steering wheel. Procuring a reliable electric start long shaft outboard secures off-grid pushing power.

• Confirm a 20-inch vertical measurement from the transom top to the keel.
• Verify the tiller handle sweep path clears your rear bench seating completely.
• Avoid oil slicks on the water utilizing modern four-stroke internal lubrication.

Ideal Application and Vessel Fitment

This 20-inch electric-start tiller engine is engineered specifically for tall-transom aluminum work skiffs, heavy fiberglass camp boats, and commercial river-running hulls demanding high thrust. By combining push-button ignition with a battery-less EFI backup system, operators gain maximum reliability for remote area fishing gear. The advanced EFI guarantees this electric start long shaft outboard fires instantly in freezing weather, making it the definitive off-grid power plant for rugged backcountry exploration.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Pleasure Warranty alongside exceptional factory support. Registered commercial applications fall under a strict 1-Year Commercial Warranty with separate terms applied to the block. Scheduled maintenance requires replacing gearcase lubricants and changing oil filters at manual-specified intervals. Always save all physical service records. Your engine serial number acts as the only way to source exact genuine replacement parts. Mulmotor provides product-information support before purchase and assistance with order-related questions.
