Propane mixes perfectly with air, with great ease, and has an octane
rating of 100. Other than that. If there is an ideal fuel, propane is
it.

The only problem I see with LPG as a fuel for boat engines is that it is
heavier than air and settles. If there is a leak in the tank or hoses,
and the tank is below deck, the bilges are going to fill up with a
pretty explosive gas. This is less of a problem on land vehicles,
because there are more ways for "escaping" LPG to vent to the open air.

Also, wouldn't the boat engine LPG fuel tank have to be a pressurized
vessel? Yet another system on a boat that would have to be watched
carefully.

We have a 500-gallon LPG tank buried in our backyard. Its presence used
to make me a bit nervous.
