Rookie Question: SeaDoo Spark Trixx Humming Noise When Turned Off


New Member

I have a 2019 Sea-Doo Spark Trixx and when the start button is pressed or, for a while after the SeaDoo has been shut down, there is a humming sound coming from the hull. Like, something electric is still running. The sound stops after a few minutes. What is this? To me, it sounds like a bilge pump, but as far as I know, this is not standard on any SeaDoo, except maybe the GTX 300. Let me know your thoughts. Cheers.
Bilge pump most likely , it should power down after 1-2 minutes in the newer models this was reduced to 15-30 seconds to save battery .
