I like it! If your new Yamaha can be adapted to run both propane and gas it would be cool. A couple of small propane tanks for the dingy should last a week or more and if for some reason you run out switch to gas. I've only used propane on the generator but it seems to run much cleaner than gas.

Not too many outboards running on propane so you'll have something to talk about regarding your slick new engine setup.

No one can ask to borrow (give them) gasoline when they run out either. Well, the could but,,,
