I have a Catalina 25. Significantly heavier and larger than your Cal. I have a 9.8 XXL Tohatsu on it. Now when my Tohatsu was in for service, I put my dinghy motor on. It was a 3.5 HP 2 stroke Mercury. This moved the boat around the harbor and in and out of the slip just fine. I would not use it to motor offshore 100 miles to windward.
My friend has a Catalina 21. For in and out of the slip he uses a little electric trolling motor. Works fine.
I would think your 2.5 HP 4 stroke would be sufficent for motoring in calm water with light winds.
