Planning a replacement or upgrade?

Use the replacement link and the applicable manuals to compare the current system with the installed equipment. Matching engine count alone does not establish that control heads, control units or harnesses interchange between generations.

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.
• Match the electronic shift and throttle output settings and engine-side connections to the engine and gearbox. This electronic/electronic configuration does not use a mechanical shift/throttle actuator or require the two push-pull cables used by KE4XG.
• 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.

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

Station expansion and setup options

KE5+ supports up to four helm control heads plus one optional wired handheld station with the appropriate components.

• KE553A — matching additional-station kit
• NM0906-00 — optional wired twin-engine handheld remote; match the socket harness and system generation.

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