Honda BF50DK4LRTC 50HP – Four Stroke 20-Inch Remote

Honda BF50DK4LRTC 50HP SOHC

The Honda BF50DK4LRTC is a premium 50HP SOHC outboard designed for demanding offshore and coastal applications across the United States. Featuring a high-displacement 808cc three-cylinder architecture and a manageable dry weight of 214 lbs, this engine delivers an exceptional power-to-weight ratio for mid-sized vessels. The 20-inch long shaft configuration is perfectly matched for deep-V center consoles and aluminum fishing hulls. Our dependable outboard propulsion systems provide the mechanical reliability necessary for rigorous daily maritime operations.

Peak operational performance for this Honda 50HP is achieved within the 5500 to 6000 RPM range, utilizing advanced PGM-FI for superior thermal efficiency. The robust 2.08:1 gear ratio translates the torque curve directly into rapid hole-shot acceleration and efficient hull planing. Built with world-class Japanese engineering, this highly corrosion-resistant marine engine incorporates excellent vibration dampening for a quiet ride across choppy coastal waters.

Technical Specifications of Honda BF50DK4LRTC

• The massive 808cc SOHC architecture provides the essential low-end torque for heavy-duty marine applications.
• Programmed Fuel Injection dynamically adjusts the fuel mixture for incredible thermal efficiency and economy.
• Remote mechanical steering compatibility offers a highly durable helm control experience for vessel captains.
• A high-capacity 22 Amp alternator keeps onboard utility lights and navigation equipment fully charged.

• Microcomputer programmed ignition ensures reliable firing and smooth idling in cold offshore maritime conditions.

SOHC Engine Architecture

The inline three-cylinder SOHC design maximizes combustion efficiency while reducing overall engine bulk for US boaters. This translates into reliable low-end torque that mariners depend on when hauling heavy fishing gear through dense coastal marshlands and strong tidal currents.

PGM-FI Induction System

Honda’s Programmed Fuel Injection continuously monitors atmospheric variables to deliver the perfect air-fuel ratio. This guarantees instant throttle response and prevents engine bogging during rapid acceleration scenarios while navigating tricky channels in the American saltwater marine environment.

Long Shaft Propulsion

The 20-inch shaft ensures deep propeller immersion on standard transoms to prevent unwanted cavitation in choppy seas. Paired with the robust gear ratio, it maximizes hydrodynamic grip to push heavily loaded pontoons and offshore skiffs across coastal bay waters.

Microcomputer Ignition Control

Equipped with a microcomputer programmed ignition, this engine delivers precise spark timing across the entire RPM band. Coupled with the 22 Amp alternator, it ensures flawless starting and reliable operation for vital marine electronics and bilge pumps during offshore excursions.

CARB Emissions Compliance

This 50HP outboard achieves a rigorous C.A.R.B. 3-Star emissions rating, making it an environmentally responsible choice for US waterways. This ultra-low emissions certification ensures clean operation without sacrificing the raw torque required for professional and recreational maritime applications.

Center Console Application

This remote mechanical outboard is the ultimate power solution for mid-sized aluminum boats and fiberglass center consoles. It provides the sustained high-end thrust needed for navigating difficult coastal tidal flows while remaining highly fuel efficient during long offshore transits.

Maintenance & Longevity

Regular inspection of the 2.1L wet sump lubrication system is critical for maintaining internal engine tolerances over the years. Always flush the cooling system with fresh water after every saltwater excursion to prevent mineral scale buildup. Pro Tip from the Shop: Regularly inspect and lubricate the remote mechanical shift and throttle linkage to prevent cable binding and ensure smooth gear engagement in highly corrosive coastal climates.
