    Hey all Glastron Gt187 jet boaters. Just checking out if you all experience a rumble at idle speed, that goes away under minimal power and higher power?

    Don’t have a Glastron but the Yamahas do that also.

    I haven't heard that. Does the rumble sound louder with the engine hatch open, or is it resonating forward in the hull?

    Sounds like it is coming forward from the rear. It's like a rumble from a low idle motorcycle.

    Thanks for your reply. Our Seadoo Spark does it at idle also. Just curious.
