A dead or damaged ECU can leave your ski stuck at the dock. This Siemens 665785 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.
To skip the $100 core charge, ship us your old ECU after ordering, along with a printed copy of the invoice.
