Launched late 2015, the Honda Intelligent Shift and Throttle (iST) is a drive-by-wire electronic shift and throttle system. Honda says the new throttle system is designed to provide flawless communication between the operator, the outboard engine and boat. Honda iST is initially available on Honda’s BF250 engine, compatible with installations of up to four engines and capable of being operated from either one or two helm control stations. The control features power trim and tilt functions and a warm-up mode that locks the gearshift in the neutral position whilst still allowing limited throttle operation.
A trolling control feature provides incremental slow-speed control which can be programmed to suit individual requirements using easy-to-operate large buttons to increase or decrease speed. Honda iST trolling speed function operates throughout the RPM range, acting like a cruise-control function at higher speeds. A Docking mode restricts throttle lever response to ensure controlled boat manoeuvring when docking or in restricted areas such as marinas. The control head allows throttle lever friction level adjustment to individual preferences and easy selection of active helm station on dual station boats. The multi-engine control unit offers all of the above features, plus engine RPM and power trim/tilt synchronisation. Once the engines have been synchronised, they will operate at the same speed and trim position, using just port hand lever and controls. A Home to Port backup system is incorporated which permits limited Honda iST operation in the event of system malfunction. An integrated on-board diagnostic system is included in the control head to reduce fault diagnostic time at the Honda dealer. Honda iST features a Start In Gear Protection mechanism which allows the engine to start even if in gear. The engine will remain in a ‘neutral position’ until the gear lever is brought back to the neutral point, therefore resetting the Honda iST ECU (Electronic Control Unit). This allows the fisherman to once again select forward or reverse gear. Installation of Honda iST has been designed to be quick and easy, with no special tools required. A plug and play communication cable runs between the Honda iST equipped engine and the control head, followed by simple system configuration if required by the customer.
