I know it is too late...but in case you keep shopping. I own a 268 SC with a 320 HP Volvo and it pulls tubes and knee boards just fine. The only time I have wished I had more HP is when the boat was full of gas, people and full canvas was on an extended cruise. It took a few more RPM's than I would have liked to cruise at speed. Other than than that, it is great. It is outstanding on gas, which comes in handy when the prices spike.
