Yamaha F175LA 175HP 4-Stroke Outboard – 20in Shaft, EFI

Description

Modern performance bay boats reach astonishing top speeds effortlessly once the Yamaha F175LA applies its massive 2.8-liter displacement to the water. The 16-valve DOHC block forces explosive midrange torque upon acceleration, pushing heavy 21-foot fiberglass center consoles across choppy inland lakes reliably. Measuring your exact transom geometry ensures this 175hp 20 inch shaft outboard fits securely without generating excessive lower unit drag.

Maintain optimal running attitudes dynamically across rough water by engaging the integrated hydraulic power trim and tilt system from your forward console. You tuck the 218 kg engine inward instantly to push the bow down and slice through morning chop safely. Yamaha engineers the midsection using specialized anti-corrosion marine aluminum alloys. This structural barrier stops rapid galvanic decay when repowering performance aluminum boats in high-salinity coastal environments.

Key Features of Yamaha F175LA

• 2.8-Liter DOHC Block: Breathes massive volumes of clean air efficiently, generating 175 horsepower effortlessly to lift heavy 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 fuel requirements continuously, eliminating carburetor hesitation and ensuring crisp throttle response across the 5500 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.
• 50-Amp Charging Alternator: Outputs constant electrical current while running, keeping deep cycle batteries topped off for commercial aerators and navigation lights.
• 1.86:1 Gearcase Ratio: Spins aggressive high-pitch propellers efficiently, translating inline-four torque directly into forward vessel momentum.
• Turn-Key Electric Start: Ignites the block instantly via your forward ignition switch, providing car-like starting reliability in freezing weather.
• Anti-Corrosion Finish: 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 F175LA

Choosing this specific engine limits installation entirely to 20-inch tall transoms rigged with standard mechanical forward steering wheels. You cannot operate this via digital fly-by-wire controls. Correcting your rigging geometry is a mandatory step when replacing older mechanical outboards.

• 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 mechanical-steer outboard excels on heavy aluminum bass boats, mid-sized center consoles, and 18-22ft performance pontoons carrying heavy payloads. By integrating a proven 2785cc displacement block with standard mechanical cable controls, the engine acts as an incredibly reliable mechanical workhorse for serious boaters. The 20-inch shaft ensures the center of gravity remains low, making this mechanical steer 175hp outboard an absolute necessity for fast bay fishing and heavy passenger hauling.

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.
