Well..Carina and I visited Mike Mullins (aka Mike Mull on FaceBook) in Winter Haven, FL for 5/6 years ago.
Did see the #33 boat but it was not ready to run. Not sure if Mike have run it or not. I have only seen it on a trailer.
The twin Evinrude V4 engines have for some reason Merc stern brackets..
