ICU – Ignition Control Unit 2016

📋 Overview & Part Info

• The ICU 2016 is identified as part number A000661 in the Jetsurf parts catalog. JETSURF Canary Islands+1

• It is marketed as the original Jetsurf ignition module for boards built up through and including the 2016 model year. motosurf.store+1

• On Jetsurf’s Canary Islands site, the listing shows compatibility mapping: it is used in some 2016 models like UltraSport, GP, Race, Race Titanium, etc.

  For example:

  Model	2016 Use?
  UltraSport	✔ (uses ICU 2016)
  GP	✔ (2016)
  Race	✔ (2016)
  Race Titanium	✔ (2016)

• Note: The listing shows for years after 2016 (2017, 2018, etc.), the ICU 2016 is not used for those model years.

• One retailer, MotoSurf Store, gives some physical‑dimension data: weight ~ 2 kg; packaging dimensions ~ 15 × 15 × 25 cm.

🛠 Features & Function (General for Jetsurf ICUs)

While I did not find a full detailed spec sheet specifically for the 2016 ICU, many of its functions are similar to other ICUs in Jetsurf boards. For example:

• It controls engine ignition, safety circuits, diagnostics, and starting logic (e.g. staging “power on → diagnostics → start”) — similar to what’s documented for other ICU models.

• It uses multiple connectors: one to the water pump, one to ignition system, ground, and others. Replacement procedure requires disconnecting about 6 connectors in total.

• The replacement procedure generally is:
   1. Wait for engine to cool and ensure ignition is off (no LED active).
   2. Remove fuel tank first (disconnecting tubes, Velcro, etc.). 
   3. Remove screws and clips holding harnesses, ground wires, disconnect connectors. 
   4. Remove the old ICU and install the new one, reattach all connectors, ensure proper fastening using thread lock as required.

• It is very important to never bring a magnetic key close to the ICU when installing/removing as it may interfere or damage the internal electronics.

⚠️ Differences

• Because the ICU 2016 was designed for the earlier generation of Jetsurf boards, it may have software, pinouts, or wiring differences compared to ICUs of later years (2017, 2018, etc.).

• The parts compatibility lists show that the ICU 2016 is not used in those later year models, meaning swapping with a newer ICU may require firmware matching or adapter harnesses.

• Buying a 2016 ICU for a 2017+ board may not work unless the board is designed to accept it, or modification is made.....
