Honda BF250DK1LDA 250HP – iST 20″ Shaft Standard Rotation in Silver

Honda BF250DK1LDA 250HP VTEC V6

The Honda BF250DK1LDA pairs a 3.6L 24-valve SOHC V6 VTEC engine with standard rotation, weighing 613 lbs dry — a strong power-to-weight ratio for mid-to-large vessels. The 20-inch shaft suits standard transoms on high-speed offshore center consoles in Mulmarine’s outboard propulsion systems lineup.

Peak output holds between 5300-6300 RPM, leveraging PGM-FI for thermal efficiency. The 2.00:1 gear ratio is built to translate torque into rapid hole-shot performance and steady hydrodynamic stability. Built with Honda’s usual Japanese engineering, this unit is corrosion-resistant and includes vibration dampening for a quieter ride on long-range saltwater runs.

Technical Specifications of Honda BF250DK1LDA

• The 3.6L V6 SOHC architecture provides strong displacement for torque and heavy-load acceleration.
• VTEC optimizes valve timing at high RPM for stronger power output and efficiency.
• iST gives precise drive-by-wire control for effortless shifting and throttle management.
• A 90-Amp alternator delivers 60 Amps of charging to support radar suites.
• Standard right-hand rotation gearcase gives efficient hydrodynamic thrust for primary engine installs.
• Programmed Fuel Injection (PGM-FI) ensures precise combustion for reliable cold-start reliability.
• Power Trim and Tilt facilitates rapid hull leveling for improved ride quality.

VTEC V6 Technology

This V6 VTEC unit uses variable timing to maximize power across the power band, holding a flat torque curve for offshore transit through difficult coastal inlets.

iST Digital Control

The iST system removes mechanical cables for a seamless drive-by-wire experience in busy harbors, giving smooth gear engagement and precise throttle adjustments.

20-Inch Propulsion Shaft

The 20-inch shaft is built for standard offshore transoms on high-performance deep-V hulls, keeping performance consistent for fiberglass fishing boats and commercial utility craft.

Marine Digital Interface

NMEA 2000 certification lets this unit send fuel, RPM, and temperature data directly to the vessel’s digital helm displays.

Honda 5-Year Warranty

Honda Marine backs this unit with a 5-year limited warranty covering major components against manufacturing defects.

Offshore Hull Match

This V6 fits mid-to-large center consoles and walkaround vessels used for deep-sea fishing, delivering sustained thrust through heavy offshore swells.

Maintenance & Longevity

Routine inspection of the wet sump lubrication system keeps the 3.6L engine’s tolerances tight. Flush the cooling system with fresh water after each saltwater mission. Pro Tip from the Shop: verify the iST digital communication harnesses stay free of moisture to prevent electronic lag during high-speed cruising.
