I am interested in building an Eagle 1 or 3 hovercraft from plans. I live in California, near San Francisco. I would like to use a 4 stroke motor, maybe a Briggs and Stratton. Would a 35 HP Vanguard motor work well with these crafts? I'm sure it would be fine with the Eagle 1, not sure if it would be enough for the Eagle 3. I would be using the craft on calm lake waters. Thanks for any help with this matter.
