The 35hp vanguard get 5.8 hrs on a 10 gal tank. The conversion cost is around $1500. But go over to the propane section. I bought two that had been converted. I did the third myself. It was a 19hp Kohler. I got a protype mount for the tank free. I bought a carb for $100, a regulator for $85. Then I begged for the hoses...and paid a little to have it adjusted. It is fancy but it works. I think hp went up but that is subjective. I like the $2.25 a gal. We put them on becase it is getting to be necessary in our area.
