A dead or damaged ECU can leave your ski stuck at the dock. This Siemens 665355 unit swaps directly into 2004-2011 Sea-Doo models to solve that.
Installation is easy: unplug the battery, swap the ECU, plug the battery back in. The key does not need to be programmed to the new unit.
There is a $100 core fee if the old ECU is not sent back to us. Include a printed copy of your invoice when you ship the core.
- Part number 665355
- Fits 2004-2011
