Honda BF100AK1XRTC 100HP 4-Stroke Outboard – 25in Shaft, VTEC

Install the Honda BF100AK1XRTC 100HP 4-Stroke Outboard when a boat requires a 25-inch shaft and carries a manufacturer-approved 100 HP rating. Its 1,496 cc inline four-cylinder engine provides practical propulsion for compatible center consoles, pontoons, and other recreational hulls carrying passengers, fishing equipment, and standard onboard loads. Honda BF100AK1XRTC combines VTEC, Programmed Fuel Injection, electric starting, remote steering compatibility, and Power Trim and Tilt. The X-long shaft is the primary distinction from the 20-inch configuration.

Before rigging, include the 379-lb dry weight in the boat’s transom and balance calculations. Rated output reaches 100 HP at 5,900 RPM, with a full-throttle range of 5,500 to 6,300 RPM for checking engine and propeller setup. The 44-amp alternator supplies 35 charging amps for supported marine equipment. The 2.33:1 gear ratio supports standard forward, neutral, and reverse operation through the remote control arrangement.
