CNG to Propane Conversion

Having started this string, I''d like to thank all that contributed. Let me recap. CNG is very safe, lasts only a few weeks in normal use, is expensive, and not available outside the US. Surprisingly (to me) CSI will supply the source of conversion to propane if you call them. I intend to call (number please).
Now let me extend the discussion. For those that have converted. Did you puirchase a prefab propane locker or build your own? What was your rationale?

No offense, how do you like it when your post is trivialized. I responded to try to help someone that had the same problem I had and overcame. I really don''t mind an honest opinion if they actually read the post and don''t quote me as saying or doing something I didn''t say or do. Thanks

have you sailed much offshore ?
if you have you will know that running into big seas is inevitable even with the best weather steerers and the best electronics. i am not proud that i sailed into 30 foot seas last fall but i am glad we survived it. i thought that some people would find it interesting.
i also have videos of us heaved to this spring in 50+ knot winds and then as the winds peaked we went to a jordan drogue. but i guess you wouldn''t be interested in that either.

I never gave any info about my propane locker set-up. Why would you assume I just changed the "jets". I know the hazards of propane just like you and everyone else who owns a boat. My "know sweat approach" easily passed survey as I bought the proper parts and materials. I see you are proud of being in 30ft waves in the gulfstream and wonder why you were caught in such conditions?

I would be happy to. I live aboard and my boat came with CNG. It was a hassle to get the cng and very expensive. It is 55$ to exchange at the marina I am at now. One tank of cng lasted me less than a month. I called CSI and even though the stove is now sold by seaward they helped me get the conversion kit. The reason you have to run a new thermostat is because the kit comes with a new oven knob? assembely and the thermostat and copper coil go into it. The orifices just screw out ands you screw in the new ones. I got the number from a plaque in the stove. As far as the locker stuff you can always hang it on your sternrail, the cost of living aboard and buying cng isn''t really an option as you almost need 2 tanks so you have gas when the other ran out.

i reviewed the guys comments who "just changed the jets in his stove". that is the suicide approach to conversion.
he didn''t even add an electrical solenoid to his tank.
you shouldn''t re jet without adding a separate locker for the propande tank
which is vented overboard, a propane sniffer, and a solenoid and switch panel as well as add gas proof connections to the propane locker. i am sure his no sweat approach would not pass an insurance survey.
i converted kimberlite to propane and it was difficult to find space for the locker.
if you are really intent on spending a lot of time cruising offshore go for it.
a rejet kit is available from corp bros in mass.
if you would like to discuss this further or see some photos of kimberlite - a completely restored tartan 37 or see some videos of us surfing some 30 footers in the gulf stream.

It seems one guy said it was easy and cheap and others say it is very difficult. We do plan to go to the islands. Could the sailor who thought it no sweat please expand his thoughts

check out the orfices before you go to replace them. many are adjustable for change over. if you take the orfice off look on the inside of the tube that you took it from and see if there is like a sharp pointed brass piece inserted in the tube that comes into contact with the orfice from the back side. tightening down the orfice reduces the flow of gas (cng) and loosening it increases gas flow (lpg). "CAUTION" LPG is heaver than air and if there are pilot lights on the appliance it may necessitate lowering the physical location of the pilot light to accomidate this condition. This also leads to why boat owners are trying to get away from lpg "heaver than air means that it will settle in the low areas of the boat and become explosion hazards". Believe me, because my dad was blown up in the basement of an old house because of this very thing.
