I just went through this myself. The boat that I purchased had a totally illegal propane system.

I found that retrofitting a boat for a proper propane system was terribly expensive. I already had an almost new LPG stove but when I added up the cost of doing the system corrently I could buy a new stove for less. If you do the system right, you are buying a long list of expensive items with a few not so expensive items thrown in: Tank (go aluminum), shut off/connector, servo-valve (solinoid), properly made up gas lines, a sniffer/shut off switch/and carbon monoxide alarm, either a manufactured pre-fab tank storage unit or else building a proper storage well (sealed air tight with a hatch that opens directly to the sky {rather than ino a locker)with a drain at the bottom and a vent at the top; Both the drain and the vent opening over the side above the heeled waterline and no electrical connections within the container), tank hold downs,and a bilge blower system.

Given that I have seen way far more boats that burned or blew up because they had propane and a diesel than I have seen gasoline engined sailboats catch fire or burn, and that like most people I would be hesitant to buy a boat with a gas engine, it seemed obvious to me that LPG was a really bad idea.

I ended up deciding to install an Origo 600 non-pressure alcohol stove/oven. (Defender Marine has the best price.) The Origo is the safest of stoves that you can buy with almost no moving parts. Alcohol is easy to store.

Origo''s do not have the dangers and poor performance of the older pressurized alcohol stoves. The Origo burners have nearly the same heat output as a Marine LPG burner and more than twice the heat output of a normal pressure alcohol burner.

I have used an Origo on my last boat for over 13 years and they are really wonderful to own. I have spent too much time in my life searching for small propane leaks, to ever want propane on a boat of mine. Beside installing the Origo was way less expensive than putting in a proper LPG system.

Another really neat system (especially if you are going offshore) is the Wallas Stove and Oven. These burn diesel fuel in sealed compartments (no oil burning smell) so you only carry diesel fuel onboard. These are really well built units and although quite expensive are still way safer and well less expensive than installing an LPG system.

Just my two cents here.

If you do decide to go to LPG, I do have a two burner LPG Hillerrange with oven that is virtually new and that I would be willing to sell you quite cheaply.

On the other hand, the trick on the Origo is to find a laboratory bottle to hold the alcohol. Also use a wooden dowel and gently slightly increase the detent in the screen. Then filling is really easy. The heat content is virtuall the same as a typical marine CNG burner and only slightly less than a marine LPG burner.

Actually, marine propane burners do not have significantly higher heat output than a catalyzed alcohol burner (such as Origo). The last time I researched this the heat output of an Origo was something like 3200 BTU''s vs something like 3500 for propane. This compares to a pressure alcohol stove at 1700 BTU''s and pressure kerosene/diesel at 4100 BTU''s. Typical CNG burners had substanially less output than either Propane or catalyzed alcohol.

People often judge alcohol based on the poor peformance and safety of earlier pressure alcohol stoves. While Propane has more heat per pound (another reason that many people eroneously think that propane burners put out more heat), it is the burner confiuration that actually determines the amount of heat that is produced.

As far as safety, I actually got a small discount on my marine insurance when I removed my propane system and went to an Origo. Catalyzed alcohol stoves do not have the risk of a flare up (if filled properly) and sure beat trying to find gas leaks, something that I have spent way too much time doing. At least in my lifetime I have seen far more sailboats lost to propane explosions than to gasolene engine explosions and yet most sailors these days would not consider having a gasolene engine. Go figure.

The stove in question is a two burner Hiller range with oven. It had one season of use during which it made a couple cups of coffee. It has peizo-electric starters and is spotlessly clean. It appears to be of all stainless steel construction. It is gimballed (technically hinged because it can only rotate on one plane and gimballed implies rotating on all planes. The stove sells for approximately $1200 new at Defender or West. I would like to get soemwhere between $500 and $600 for it.
