Honda BF250DK1UCDA 250HP 30in iST Counter Rotation in White Outboard Motor

Description

Propel deep-transom offshore hulls using the Honda BF225 iST Outboard Motor BF225DUDA configuration engineered for center consoles, catamarans, and patrol craft. Displacing 3.6 liters across six V-arranged cylinders, this power plant produces 225 brake horsepower at 5500 RPM. Intelligent Shift and Throttle drive-by-wire controls pair with a 30-inch shaft for responsive high-seas navigation.

Cast from corrosion-resistant marine aluminum alloy, this block features single overhead camshafts activating 24 valves with VTEC variable valve timing. Raw sea cooling incorporates sacrificial zinc anodes and dual freshwater flush ports. Fuel lines connect to a standard 3/8-inch hose barb, while electrical power flows from a high-output 90-amp alternator. Dry engine weight measures 630 lbs, clamped over a 30-inch transom with an 8.0-quart engine oil sump.

Key Features of Honda BF225DUDA

Custom boat builders buy Honda BF225DUDA outboard engine packages to gain digital fly-by-wire throttle control and high-displacement V6 power. The 3.6-liter platform generates strong low-end torque to lift loaded hulls onto plane with ease without stern squat.

• Multi-port programmed fuel injection meters fuel micro-charges to eliminate smoke during slow harbor trolling passes.
• VTEC variable valve timing refines BF225DUDA high-rpm power output across aggressive open ocean cruise speeds.
• High-flow rubber impeller raw pump circulates 28 gallons per minute through the powerhead cooling jacket.
• Heavy rubber shear mounts absorb engine vibration before reaching transom knees and aluminum hull plates.
• Spin-on engine oil filter allows clean filter swaps without spilling fluid into coastal waterways.
• Through-propeller underwater exhaust hub lowers outboard operating noise during passenger harbor transit runs.
• NMEA 2000 digital communication protocol exports engine metrics straight to multi-function helm chartplotters.

Torque Dynamics Marine Thermal Thresholds

Producing 223 lb-ft torque at 4,500 RPM, this VTEC-equipped V6 four-stroke outboard accelerates heavy offshore craft onto plane in seconds. Operating coolant temperatures stay regulated between 140°F and 160°F under continuous cruising throttle. Programmed electronic fuel injection ensures uniform cylinder combustion pressure, preventing thermal fatigue on valves and piston crowns. Sea water heat rejection totals 7,200 BTU per minute at full rating. Cruising fuel consumption records at 0.365 lb per horsepower-hour, maximizing operating range between remote fuel dock stops.

Transom Stringer Rigging Installation Clearance

Mounting over standard transom stringer knees requires a minimum 2.5-inch clearance from the clamp bracket base. Exhaust discharges through the propeller hub meeting ABYC P-1 standards, with idle relief ports clearing dynamic waterline by 6 inches. Heavy elastomer motor mounts isolate steering torque while maintaining shaft depth on 30-inch transoms.

Shift Routine Scheduled Maintenance Protocol

Electronic drive-by-wire helm levers provide instant gear engagement when maneuvering around mooring buoys and shallow docks in gusty crosswinds. This four-stroke marine outboard is not engineered for non-stop continuous barge towing, untreated sand slurry dredging, or uncooled dry exhaust operation without raw sea water cooling.

• Inspect water pump telltale stream and check lower gearcase oil level each shift.
• Drain primary fuel water separator bowls and examine engine oil dipstick levels every 50 hours.
• Replace engine fuel filters and inspect external gearcase sacrificial zinc anodes every 250 hours.

Factory Crate Shipment Warranty Manifest

Honda covers this outboard with a True 5-Year non-declining recreational or 1-Year commercial factory limited warranty. The heavy cardboard export crate contains the complete outboard motor, four transom mounting bolts, an electronic helm wire harness, an owner manual, and an official factory technical service guide.
