There is a "how to" discussion on the Honda generator newsgroup about converting them to propane. It is pretty straight forward so I wonder if any 4 stroke could be converted using the same parts. The advantage to conversion would be having the ability to burn both fuels. I'm still waiting for my 2 stroke to give up the ghost which from the way it sounds could be anytime before I graduate to 4 stroke.

I can't see it for main engines (given the difficulty in getting refills, you would need to carry 200 pounds if you cruise far--I've burned 100 pounds in a day), but I can see it for tenders. Some folks would like the feel of security. They're going to sell some, for sure.

I know that local service trucks have been converted to burn propane. I would like to know more precisely what the equivalant consumption rates are between gasoline and propane.

This might appeal to the gasophobes out there; better one evil than two.

On a BTU basis it's about 5.2 pounds of propane to equal one gallon of gasoline. Propane is typically about $0.75/pound at the refill place. So, about $3.90/gallon.

At least on a cat, gasoline is no greater a threat than in a car, in my eyes. If I had an engine and tanks in the hold, I would be more concerned. Personally, I think good fuel management is simpler...

... which brings me to this (skip ahead to the very end of the post):

Apparently open fuel tank vents will become a thing of the past, and this is probably a good thing for us. Less water absorption, less fuel evaporation, and less oxygen exposure should mean better fuel.
