On the West side of the state where I will be sailing, we do get some serious chop on the Lake Michigan.
This Irwin belonged to my father, and I sailed it as a kid. Then he sold it when he became sick (over a decade ago). I found it last fall on the other side of the state, and had to buy it. I have been looking through photos and have not found one that has a picture of the motor. If I could figure out what he had, then I would know for sure what to get. He always seemed to go for the smallest motor that would do the job.
