Description
Shallow-water navigation becomes completely effortless once the Yamaha F20LWPB connects to your forward steering console. The advanced 432cc inline-two EFI block translates electric starting power into immediate forward thrust, pushing deluxe fiberglass skiffs across choppy inland lakes reliably. Verifying your exact transom geometry ensures this 20hp remote steer power tilt outboard fits securely without generating excessive lower unit drag.
Lift the gearcase completely clear of mud flats instantly by utilizing the integrated hydraulic power tilt system. You adjust the running attitude directly from your helm switch to protect the propeller against hidden oyster beds. Engineers cast the 63 kg midsection using specialized anti-corrosion marine aluminum. This structural barrier stops rapid galvanic decay when repowering premium coastal runabouts for daily saltwater exposure.
Key Features of Yamaha F20LWPB
- 432cc Inline-Two Block: Breathes clean air efficiently to produce massive low-end torque, lifting heavy fiberglass runabouts onto plane much faster.
- 20-Inch Standard Shaft: Matches tall high-performance transoms perfectly, keeping the gearcase profile tight to maximize top-end running speeds.
- Hydraulic Power Tilt: Lifts the gearcase completely clear of mud flats at the push of a button, preventing catastrophic propeller strikes.
- Remote Steering Bracketry: Accepts standard mechanical cables directly from your forward helm, integrating flawlessly for precise directional control.
- Electronic Fuel Injection: Vaporizes gas instantly into the cylinders regardless of temperature, guaranteeing crisp throttle translation on lightweight fiberglass hulls.
- 16-Amp Charging Alternator: Keeps your cranking battery topped off automatically, powering demanding fish finders and livewell pumps reliably all day.
- Turn-Key Electric Start: Engages the flywheel instantly via 12-volt battery power, eliminating physical pull strain completely during freezing early morning launches.
- 2.08:1 Gearcase Ratio: Multiplies engine torque effectively, translating the 432cc displacement into relentless pushing force for loaded sport skiffs.
- Anti-Corrosion Castings: Blocks severe galvanic decay physically, protecting the aluminum powerhead block across decades of daily saltwater exposure.
- Clean Four-Stroke Combustion: Burns fuel highly efficiently without oil mixing, easily meeting strict local waterway emissions regulations and EPA standards.
Why Choose Yamaha F20LWPB
Choosing this specific engine limits installation entirely to 20-inch tall transoms rigged with forward steering wheels and power tilt requirements. You cannot bolt this onto a tiller-steered skiff. Correcting helm geometry is a key step when finding a reliable 20 inch shaft outboard replacement.
- Measure the vertical distance from your top transom edge to the keel bottom.
- Install corresponding mechanical control cables sized exactly for your specific boat length.
- Keep coastal waters clean by running highly regulated four-stroke engine configurations.
Ideal Application and Vessel Fitment
This 20-inch remote-steered outboard excels on deluxe fiberglass runabouts, high-transom aluminum console boats, and compact side-console pontoon logs requiring push-button tilt. By connecting directly to a forward helm station, it shifts the operator weight forward, drastically improving the vessel running attitude and time-to-plane. The 20-inch shaft guarantees the water pump remains deeply submerged on tall transoms, providing a safe propulsion solution for recreational boaters needing a remote steer tohatsu outboard motor.
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 zero corrosion coverage 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.
