Those 4 strokes have a pretty deep gear ratio to them in the lower unit.

Ok, local marinas looking to see what they have for props. One said YES over the phone to several 21p test props and when I showed up in person you would have thought I was speaking Russian, Nyet!!.
Raising the motor to the highest position on the bracket, Friday. That idea is genious. Tweaking on the throttle plates to adjust idle down a bit.
My motor guru claimed mid-50's. He stated that I would be fighting the wind with my t-top and console as it is currently set up.
Since I have totally hijacked this thread I would offer that a light 20 with the proper setup and 250hp would be able to achieve 60mph without question. It would be cool to start with a CC and install a small console all the way to the step for the casting platform.
Bare essentials with a bucket seat that just offers a view over the bow.
Or maybe a cuddy with a small windscreen. 60 would probably arrive with less than 250 hp if the hull was light enough.
