Just get a boat and put whatever ya want in the back. Only the TFF lawyers give a [censored]. Lol. I just finished putting a LS8 supercharged crate motor in a ‘70 Chevelle. 700-990hp depending on fuel and tune. I don’t think the insurance companies give a damn either way that it now has triple the original power. I’m sure a boat rated for 200 or 225 will simply be BETTER with a 250. Same weight on the transom, gonna fish the same, same length on the trailer, it’s just gonna holeshot and handle better.
Well that won’t work if you take your Chevrolet to the drag strip in a sanctioned race. Your horsepower will matter which class your in.
In a fishing tournament over horse powered is not allowed either.
