KE751 Twin-Engine Electronic Control Kit — Chrome, Composite Trim/Tilt Levers

KE7+ · electronic shift and mechanical throttle

The NHK MEC KE751 is a KE7+ electronic marine engine-control base kit for two engines and one helm station, with electronic shift and mechanical throttle connections. The chrome control head has composite trim/tilt levers.

• Product type: Single-station base kit
• Engine configuration: two engines; electronic shift and mechanical throttle
• Lever style: composite trim/tilt; chrome control head
• Order separately: Two bus-harness sections and 2 mechanical throttle cables

Why choose KE751?

• Bring shift and throttle together. Use one lever for each engine.
• Replace older controls. For an older electronic, Hynautic hydraulic or pneumatic installation, confirm the engine and gearbox connections first. Match the new system to the engine’s mechanical throttle and gearbox’s electronic shift connections before choosing the installation parts.
• You want less upkeep at the helm. Electronic commands avoid control-system hydraulic fluid bleeding or control-air pressure maintenance. Routine connection checks, cable checks and actuator care still apply.
• You want dependable controls. Neutral-start protection and fault indication support normal operation and troubleshooting.
• You might add a station in the future. Expand with matching station components and harnesses when another operating position is needed.

Required separately and installation planning

• NM0649 bus harnesses — select two sections for the standard twin-engine, single-station layout. Confirm each route length against the applicable wiring diagram. Bus, power and engine-interface harnesses have different roles.
• 2 × CCX633 mechanical engine-control cables — one throttle cable per engine, selected for the actuator-to-engine or gearbox route.
• Configure the system using the control-unit settings described in the applicable legacy manual. Do not apply KE-XG programming instructions to a different generation.
• The listed power harnesses are 5m. Optional 10m power harnesses can be discussed when requesting the complete system quote.
• The listed 5m shift-signal harnesses are the standard kit lengths; compatible 10m shift versions are optional. Select these separately from the CANbus routing length.
• The applicable manual limits the total CANbus-harness run to 80m. Plan the complete layout rather than treating this as the allowance for each section.

Request complete system pricing to include the required harnesses, cables and other installation parts.

Station expansion and setup options

KE7+ supports up to four helm control heads plus one optional wired handheld station with the appropriate components.

• KE751A — matching additional-station kit
• NM0906-00 — optional wired twin-engine handheld remote; match the socket harness and system generation.

Optional emergency mechanical backup: the actuator’s manual-operation arrangement requires the separate mechanical control head and cable components described in the applicable manual. These optional components are not included in the kit.

Planning a wireless docking remote? Ask Seatech to confirm the remote model, compatible control-system interface and additional hardware before ordering.
