I can go 90% throttle no problem for hours but anytime I go full throttle i get the alarm at a constant beep. Can someone plz tell me what to check to diagnose? I have just replaced impeller changed lower unit oil and spark plugs. Don’t know if that helps but I think it’s safe to say the stream if good for sure.

Where do I mount the tow bar so I can pull a tube and which tow bar is recommended?
