Re: Got my hands on the new propane outboard today...
His price for propane is about right for here (maryland), his price for gas is somewhat low (even using his original price of 2.85 which became 2.65 in his calculations.
Using the current (July '13) average around here - 3.39 it is still less expensive to run with gas than propane. It actually costs 38 percent more to run propane given those numbers.
Cost is not the only issue - cleanliness, emissions, sound, easy of use, risk mitagation etc. need factored in.
Practical Sailor magazine rated this engine as measurably louder than the gas version. They also said it was less powerful at WOT (not a real issue as most dinghy's reach hull speed at 2/3 throttle with a 2.5 hp).
Emissions, it's still a green house gas emitter. Cleaner, not zero.
No build up in the carb.
Handling propane is a known factor, like gas - to me that's a wash.
The only kicker I see left is cost (MUCH more expensive)- and using my limited propane for anything but cooking. A hour of dinghy time (1 pound estimated) comes out to at least several days of cooking gas.
Lessons learned are opportunities earned.
