The Honda BF 225 DK1 UDU is a 4-stroke outboard marine engine designed for medium to large fiberglass or aluminum boats, private yachts, and multi-person touring boats requiring an ultra-long shaft. It features a 225 HP / 165 kW, 3583 cc V6 SOHC VTEC PGM-FI engine. The BF 225 DK1 UDU, with its 3583 cc V6 SOHC VTEC engine, offers a balance of power, efficiency, and longevity to users of medium and large boats.
The V6 VTEC system provides fuel economy at low RPMs and a wide power band at high RPMs. The 24-valve structure combined with PGM-FI electronic injection offers significant consumption advantages compared to 2-stroke alternatives.
The ultra-long shaft (635 mm (25")) keeps the propeller at an optimal water depth on large yachts and professional boats with deep transom designs. Incorrect shaft selection will either leave the propeller out of the water or cause it to hit the bottom — verify your boat's transom measurement before installation.

4-stroke Honda engines run problem-free for many years with regular oil changes and end-of-season maintenance protocols. The impeller of the water-cooled system should be checked every 100 hours or every two seasons. Freshwater flushing is mandatory after every use in saltwater.

The 225 HP V6 power is optimized for 6–9 meter medium and large boats. The PGM-FI injected V6 structure offers fuel efficiency advantages on long routes.
VTEC (Variable Valve Timing and Lift) changes valve timing according to engine RPM. It provides fuel economy at low RPMs and maximum power at high RPMs. This automotive-derived Honda technology has proven its reliability in the marine segment.
Trim adjusts the angle of the boat in the water to optimize efficient navigation — saving fuel. Tilt, on the other hand, fully raises the engine; it is used for entering shallow waters and docking. With the electric system, both operations are performed with a button.
Honda outboard motors are compatible with most Zodiac, Ribeye, Highfield, Bombard, Sea Eagle, and local brand inflatable boats thanks to their universal transom clamp system. The only criteria are your boat's 635 mm (25") transom height and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
Share your boat model, transom height, and intended use — let's verify the suitability of the Honda BF 225 DK1 UDU engine for your boat and the correct shaft selection together.
Honda's BLAST (Boosted Low Speed Torque) system optimizes ignition timing at low revs, generating extra torque during takeoff and acceleration. This allows for faster recovery, especially when maneuvering under load. This results in a safe and controlled ride in both fishing boats and long-hulled fiberglass vessels.
With Lean Burn Control
Intelligent Fuel Management
Lean Burn Control measures the engine's required combustion mixture in real time at cruising speed, applying a more refined combustion profile. This significantly reduces fuel consumption on long journeys, while also keeping the engine cooler and more stable. It offers a noticeable advantage in terms of range, especially for summer boaters and commercial vessels.
Multilayer Honda
Corrosion Protection
Honda Marine hulls are protected by a multi-layer electroplating system developed to withstand saltwater and humid environments. The aluminum alloy block, zinc anodes, and special surface coatings work together to delay corrosion for years. Even in boats that spend a lot of time at sea, the engine's exterior and internal components remain durable, extending maintenance intervals.
