I have a few questions......I have a 73 winner fishing boat with a locked up 50 Hp Johnson motor. The Hp rating is 65 hsp on the plate on the back of the boat. I have a much newer 90 Hp Mercury I would just love to put on this boat but I know I shouldn't because of the Hp rating on the plate. I have seen a ton of boats just like mine,same year and size, with much larger motors (150 range)than 90 Hp. Here's the questions............Are these people ignoring the plates on their boats and putting bigger motors on them? Are you allowed to go a little bigger on the motor than what the plate states? I'm not one for doing anything wrong.......or stupid for that matter and any advise would be appreciated.
