KE603 Single-Engine Electronic Control Kit — Chrome, Stainless-Steel Lever

KE6+ · mechanical shift and electronic throttle

The NHK MEC KE603 is a KE6+ electronic marine engine-control base kit for one engine and one helm station, with mechanical shift and electronic throttle connections. The chrome control head has a stainless-steel lever.

• Product type: Single-station base kit
• Engine configuration: one engine; mechanical shift and electronic throttle
• Lever style: stainless-steel; chrome control head
• Order separately: One bus harness and 1 mechanical shift cable

Why choose KE603?

• Bring shift and throttle together. Use one lever for gear selection and throttle.
• 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 electronic throttle and gearbox’s mechanical 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.

Included in the KE603 kit

• 1 × NM0647-11 — KE+/XG T-Harness (Single) with Terminator
• 1 × NM0666-05 — Throttle Harness - 5 Meter
• 1 × NM0667-00 — KE-6/7+ - Actuator Harness
• 1 × control-head buzzer: NJ0251-00 for 12 V or NJ0515-00 for 24 V

Required separately and installation planning

• NM0649 bus harness — select one section for the single-engine, single-station layout. Confirm each route length against the applicable wiring diagram. Bus, power and engine-interface harnesses have different roles.
• 1 × CCX633 mechanical engine-control cable — one shift 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 throttle-signal harness is the standard kit length; compatible 10m throttle 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

KE6+ supports up to four helm control heads plus one optional wired handheld station with the appropriate components.

• KE603A — matching additional-station kit
• NM0907-00 — optional wired single-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.
