I have 2015 Yamaha AR192 jet boat. Unable to get the boat on plain. When I give it full throttle it only goes about 20 mph at 6k rpms. There is not much vibration and the clean out plug is set correctly. Batteries are fully charged as well. Impeller and drive shaft replace a few months ago. Not sure what else could cause this issue. Any advice welcomed.
 
Is the boat clean?
Are you CERTAIN the plug is in correctly?

Yes, the boat is clean and the clean out plug has been set correctly. It sets all the way down and I can lock it in place.
 
seems like i've read that 6k is around max rpm if there's a supercharger clutch problem..?

Yeah, I was afraid of that. I will check to see if the clutch spins in both directions. Thanks
 
Also check to see if there is loose foam sound insulation near the airbox... I had the same thing happen on my 2020 AR195 and all I had to do is cut out the strip of insulation and it was solved
