If the Sea-Doo doesn't react at all when you press the start button, it's rarely due to engine damage. Most of the time, it's simple causes that can be checked in a few minutes.
The Most Common Reasons
A weak or incorrectly connected battery is at the top of the list, followed by the DESS safety key not being recognized correctly, and an open fuse. An error code in the background can also prevent starting, without a warning light immediately appearing.
Check Quickly and Safely
Instead of replacing parts on suspicion, it's worth taking a look at the fault memory first. With M-JET DIAGNOSTIC, you can see in a few seconds if a code is stored and which component is affected, before you unnecessarily invest time or money.
