I'm not sure this hassles of a propane outboard are worth it. For weekend cruising in North America where the outboard goes long periods between use, I really think that propane makes sense as it helps with the problems of ethanol in fuel now.
However, for liveaboard
cruising where you're using the outboard almost daily, freshness of the fuel, and the problems of ethanol in the fuel are far less of an issue. A cheap
filter bolted to the transom and a filter when filling your Jerry cans from dodgier sources will resolve 98% of the issues of a petrol engine
vs a propane one IMHO. Running the carb dry of fuel before longer crossing also helps to prevent issues from drying fuel in the carb.
In the past almost 2 years of cruising with our 2 teenage kids
and a 4 hp - 4 stroke
and a 15 hp - 2 stroke
(we've got a spare inflatable dinghy
to give the kids
some freedom when we're in places with a lot a lot of other kid boats), I've literally spent maybe 45 minutes total cleaning
the carburetor (and almost entirely from not following my own advice above) on the 4 hp outboard twice. That's far less time than I'd have spent gravity draining propane bottles and running rental bottles back and forth, not to mention potentially having to leave a more remote
island earlier than we'd have liked to because we ran out of propane.
That said...one of the advantages of a Lehr out here is that i think it's highly unlikely it would ever get stolen. :-)
Either way....good luck and I hope you get away next year!
