The other day I was really testing the sled on a lake. After getting it up to 100mph I noticed numbers flashing on the digital display where the milage is normally showing. It said something like -M64 then the numbers would go up and down, from around 70 to 40. The owner's manual doesn't mention this at all.... Is this some sort of trouble code or something telling me to slow down for some reason. The engine temp seemed fine, no lights flashing or alarms beeping. Can anybody explain this?
EDIT: its a 2006, not a 2007
