seacraft 25 cuddy

[Ken Kurek]

I have recently purchased a 1971 25' seacraft seafari cuddy with an I/O and I am in the process of repowering with a 454 cu in. How much speed and fuel consumption should I expect as it holds approx 110 gallons of fuel and the fishing grounds are approx 25 miles from where the boat is kept. Any response would be greatly appreciated.
