Tom..
I towed the Yukon down to Porters Lake (NE of the city) this afternoon and
got a chance to open it up.
My Garmin GPS says I reached 25.7mph.
The boat seemed to come up & level out around 14-15 mph and that seems like
a nice easy cruise speed for it.
It's a long lake, I had to go under 3 highway bridges, so coming back due
south I was facing into the wind and some chop. The boat dances over the
smaller stuff (under 1 foot) I may remove the rod holder next to the seat
as it interfers with the swival action.
Anyway , it was a great run, I had sections of the lake all to myself
without a boat in sight.
