Guys,<br />I wanted to know what the actual propshaft HP would be on an old Early 70's model 115HP Evinrude. <br /><br />I was looking at a boat with one of these on the back and wondered what the actual HP was and if it would be enough for skiing and tubing. I just sold my 65hp Evinrude, so to me it would be more hp. I just wasn't sure if it will be enough. BTW boat is a 74 Checkmate. Thanks
