Yamaha F40LEHA 40HP Outboard – 20in Shaft, Tiller

Description

Commercial river operations demand the heavy-duty Yamaha F40LEHA to push massive payloads upstream reliably. The 747cc inline-three EFI block atomizes gas instantly regardless of air temperature, allowing utility operators to navigate dangerous twisting river channels with crisp throttle translation from the tiller. Taping your exact transom validates this 40hp long shaft tiller outboard fits perfectly without dragging the lower unit into shallow mud flats.

Clear submerged oyster beds safely in skinny water by utilizing the integrated hydraulic power trim system as an immediate physical lifting aid. You adjust the hull attitude directly from the tiller handle to optimize your running draft effortlessly. Yamaha builds the 102 kg midsection using specialized anti-corrosion marine aluminum. This thick-wall casting survives severe structural fatigue when repowering commercial skiffs in harsh coastal environments.

Key Features of Yamaha F40LEHA

• Hydraulic Power Trim: Lifts the gearcase completely clear of mud flats at the push of a button, preventing catastrophic propeller strikes in shallows.
• 20-Inch Long Shaft: Places the anti-ventilation plate deeply beneath tall utility transoms, preventing water pump starvation in heavy chop.
• Turn-Key Electric Start: Engages the flywheel instantly via 12-volt battery power, eliminating physical pull strain completely during freezing early morning launches.
• Electronic Fuel Injection: Atomizes fuel perfectly using advanced computer mapping, guaranteeing reliable cold-weather starts and crisp throttle response.
• Multi-Function Tiller Handle: Concentrates shift, throttle, and tilt inputs directly into your operating hand for immediate physical obstacle avoidance.
• 17-Amp Charging Alternator: Outputs constant electrical current at cruising speeds, keeping deep cycle house batteries fully charged for heavy-duty marine electronics.
• 747cc Inline-Three Block: Produces exceptionally smooth power internally, eliminating the harsh vibrations typically found in twin-cylinder portable outboards.
• 2.00:1 Gearcase Ratio: Multiplies engine torque effectively, translating the 747cc displacement into relentless pushing force for heavily loaded commercial skiffs.
• Anti-Corrosion Finish: Blocks severe galvanic decay physically, protecting the aluminum powerhead block across decades of daily saltwater exposure.
• Clean Four-Stroke Combustion: Burns fuel with strict efficiency, guaranteeing peak performance while meeting modern clean-air environmental standards globally.

Why Choose Yamaha F40LEHA

This specific build fits only 20-inch transoms requiring direct physical tiller control paired with power tilt capabilities. You cannot wire this to a forward console steering wheel safely. Correcting your rigging geometry is a mandatory step when replacing older tiller outboards.

• 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 power-tilt tiller outboard excels on premium aluminum fishing boats, deep-transom skiffs, and heavy displacement Jon boats requiring reliable 4-stroke tiller power. By integrating an oversized 747cc displacement block with a high-output 17-amp alternator, the engine acts as an incredibly efficient mechanical workhorse. The integrated power tilt allows captains to lift the massive gearcase safely in shallow water, making this power tilt yamaha outboard motor an absolute necessity for coastal anglers.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Limited Warranty alongside exceptional factory support. Registered commercial applications fall under strict factory guidelines 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 can assist with product details and order-related questions before purchase.
