My Buddy's got an 18' Baker tunnel, but it has a 200Yamaha on the back of it. It does 72 on the GPS, with one person and all the gear out of it. It's pretty scary at WOT, likes to chine walk all over the place. But then again this is an outboard boat not jet. I know there was a guy on hotboat that had a jet baker tunnel and he put ALOT of work into it
