i have a 85lb snomo engine and a 45lb deck and me (130lbs)

Hmm. Don't know. I think you need to research the prop you'll use. You want to get one with as much thrust as possible. They sell hovercraft specific ones online, for like $100-200.

I've had a plan for a few years of making one using a plywood deck, lawnmower engine and (very) large innertube. Keep me posted on your progress. Perhaps you could more fully explain your plans.

It depends on the HP of the Yamaha engine? Is that the 4 cycle 40 horsepower engine??

Still not enough information. We also need the physical size of the hovercraft and how high off the ground you want it to go. Try playing with this calculator for a bit: http://www.olshove.com/HoverHome/hovcalc.html
