Honda BF100AK1XRTC 100HP 25in Four Stroke Remote Outboard Motor

Description

Corrosion-resistant marine alloy defines the Honda BF100 Four Stroke Outboard BF100AK1XRTC model engineered for offshore center consoles, catamarans, and patrol launches. Displacing 1.5 liters across four inline cylinders, this updated K1 series plant produces 100 brake horsepower at 5900 RPM. Programmed fuel injection pairs with a 25-inch shaft to ensure continuous propeller bite in rough offshore following seas.

Poured from corrosion-resistant marine aluminum alloy, this block utilizes a single overhead camshaft activating 16 valves with VTEC variable valve timing. Raw sea cooling features 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 44-amp alternator. Dry engine weight measures 377 lbs, mounted over a 25-inch transom with a 4.4-quart engine oil sump.

Key Features of Honda BF100AK1XRTC

Commercial skiff builders buy Honda BF100AK1XRTC outboard engine packages to secure high transom freeboard and four-stroke fuel economy. The 1.5-liter four-stroke platform produces flat mid-range torque to move loaded hulls through coastal chop with ease.

• Multi-port programmed fuel injection meters fuel micro-charges to eliminate smoke during slow harbor trolling passes.
• BLAST boost technology advances ignition timing to refine BF100AK1XRTC hole shot acceleration when climbing onto plane.
• Gear-driven rubber impeller raw pump circulates 18 gallons per minute through the powerhead cooling jacket.
• Heavy rubber shear mounts absorb engine vibration before reaching transom knees and fiberglass hull transoms.
• 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 98 lb-ft torque at 4,000 RPM, this 25-inch outboard accelerates deep-V hulls 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 3,800 BTU per minute at full rating. Cruising fuel consumption records at 0.380 lb per horsepower-hour, maximizing operating range between remote fuel dock stops.

Transom Stringer Rigging Installation Clearance

Mounting over high-transom stringer knees requires a minimum 2.0-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 25-inch transoms.

Shift Routine Scheduled Maintenance Protocol

Mechanical remote control cables provide crisp throttle and shift 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, a remote control cable bracket kit, an owner manual, and an official factory technical service guide.
