Outboard Suggestion
I sail on the Great Lakes, mostly on Lake Erie. When I bought the boat several years ago it had a 4.5hp Merc long and if it was blowing more than 15 knots, with the waves, we had to motor sail out of our harbor. I quickly replaced it with a 4-stroke 5hp Honda longshaft. The big difference is the torque, it just doesn't slow down in waves and we can motor out of the harbor in any conditions. We do several regattas that require us to deliver the boat 40-70 miles, and if the weather is nasty, I know that the Honda will get us off a lee shore if we need to. The added benefit is the miserly fuel consumption. We get more than 50 nautical miles out of 3 gallons at full throttle. It weighs about 5lbs more than most 4.5's, performs better than 6's, and is more than worth the extra heft.
