A dead or damaged ECU can leave your ski stuck at the dock. This Siemens 665786 unit swaps directly into 2004-2011 Sea-Doo models to solve that.
You only need to disconnect the battery, install the new computer and reconnect power. There is no DESS key pairing to do afterward.
We charge a $100 core deposit unless the original ECU comes back to us; enclose your printed invoice with it.
