Description
Modern fiberglass flats boats achieve stunning visual appeal and instant holeshot acceleration when the Pearlescent White Yamaha F70LB2 hits the transom. The 1.0-liter inline-four EFI block vaporizes gas perfectly, pushing lightweight skiffs across choppy morning bays without carburetor hesitation. Measuring your exact mounting height guarantees this white 70hp remote steer outboard operates efficiently without starving the internal cooling intakes.
Protect your investment from severe cosmetic sun damage by leveraging the exclusive Pearlescent White marine paint finish as a physical UV barrier. You reflect intense ultraviolet rays physically while navigating crowded harbors via precise remote mechanical steering. Engineers build the 115 kg assembly using specialized anti-corrosion marine aluminum. This structural upgrade stops rapid galvanic decay when repowering luxury fiberglass skiffs in high-salinity coastal environments.
Key Features of Yamaha F70LB2
- Pearlescent White Finish: Reflects intense ultraviolet sunlight physically, preventing cosmetic fading and matching premium fiberglass hull finishes perfectly.
- 1.0-Liter Inline-Four Block: Breathes massive volumes of clean air efficiently, generating 70 horsepower effortlessly to lift light fiberglass hulls onto plane.
- 20-Inch Standard Shaft: Matches standard high-performance transoms perfectly, keeping the gearcase profile tight to maximize top-end running speeds.
- Electronic Fuel Injection: Calculates precise air-fuel ratios continuously, eliminating carburetor hesitation and ensuring crisp throttle response across the RPM band.
- Hydraulic Power Trim: Adjusts the running angle dynamically via a console switch, optimizing bow attitude across aggressive offshore swells.
- Remote Mechanical Control: Accepts standard mechanical cables directly from your forward helm, integrating flawlessly with classic steering consoles.
- 16-Amp Charging Alternator: Outputs constant electrical current while running, keeping deep cycle batteries topped off for commercial aerators and navigation lights.
- 2.33:1 Gearcase Ratio: Spins aggressive high-pitch propellers efficiently, translating inline-four torque directly into forward vessel momentum.
- Anti-Corrosion Castings: Blocks severe galvanic decay physically, protecting the aluminum powerhead block across decades of daily saltwater exposure.
- Clean Four-Stroke Combustion: Eliminates messy two-stroke oil reservoirs, keeping your bilge completely clean while meeting strict clean water standards.
Why Choose Yamaha F70LB2
Choosing this specific white-finished engine limits installation entirely to 20-inch tall transoms rigged with forward steering wheels. You cannot operate this via a tiller handle safely. Correcting your rigging geometry is a mandatory step when seeking a reliable white 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 premium flats boats, white fiberglass skiffs, and lightweight center consoles where aesthetics matter deeply. By integrating a proven 996cc displacement block with the striking Pearlescent White finish, the engine acts as an incredibly reliable mechanical workhorse that complements premium boat designs. The class-leading power-to-weight ratio makes this white 70hp outboard motor an absolute necessity for fast coastal angling.
Warranty, Support and Maintenance
Authorized recreational operation receives a 3-Year Limited 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.
