I used to own a 97 240 which was based off of that hull. (May even be the same.) It was a great boat for the lakes. I found that being a sit down boat it was difficult to get comfortable when I started running over 74 mph. Along the 60-65 mark it handled very well and was a fantastic boat for day boating. I have used the cabin in the past and it was a bit tight.
I started out with a stock 7.4 and moved up in power. Great boat for the money. Just be sure to get a survey.
