My 2018 AR195 is only doing 6K RPMs and about 18 MPH at top speed. I’m new to jet boats; looking for help. I bought it from an individual about 4 months ago.

Well you down in power/RPM for sure.........Yamahas are notorious for Spark plug problems........sometimes a plug or two can be weak and still feel fairly smooth running. So if you have not changed them that would be the first thing I would do. Now theirs a lot about your boat I dont know like Stock motor or Supercharger ect............If she is a SC motor you list of possible ways to loose power is going to get a lot longer.

Start with the plugs and cross fingers.
