I'm inclined to go with either the Tohatsu 3.5 HP (also 41lb like the 2.5HP) or the Honda 2HP engine. They are around the same price, but the Honda has a centrifugal clutch instead of a true gear shifter, and is 13 lbs lighter. I haven't been able to find any good calculations of boat speed in various conditions for any of the sub-10HP motors -- anyone know of a good resource for that?

I'm looking for something that would be able to make reasonable, controlled headway against 20-25 knots of wind and the associated chop (depending on wind direction it might be nearly impossible to sail into the break wall channels under those conditions -- anything worse I'd really not consider being out in and it might be hard to keep the prop in the water).
