It’s frustrating to read about these folks having these issues with a really cool boat. There has got to be a simple answer to this issue somewhere, you don’t get a 1000 rpm drop from an oil change that is done correctly.
Also, what fuel / octane are you running?Piggy backing on this thread. My 2018 AR210 is having the exact same problem with the same engines with 70 hours. I pulled it out of wet slip, scrubbed the entire hull, changed oil/ sparks. Oil level is maybe a little bit high but nothing crazy. Running 7500 RPM and only getting 30-33 mph. In TN so elevation is low. Impellers are fine. Is there a trim setting I'm missing or a throttle cable thing? I'm at a loss.
