RE: [Electric Boats] Gas vs. Diesel

 


I tend to agree with that.
 To me the best argument fo a diesel is the economy, on larger engines, it's typically greater than an equivelent gas engine, I'm not sure if that holds true with smaller generator sized engines. Gasoline and spare parts for gas engines are generally available in more places, and are generally cheaper.
 I've always felt that gasoline could be just as safe, I mean I ride motorcycles with 5 gallons right between my legs.
 The primary requirement is good ventilation and drainage. On my Ariel, the OB and fuel tank are in the stern lazerrette, which could be considered bottomless so any vapors are able to drain overboard. (outboard 'plug' removed opens up a roughly 12"x12" hole in the stern counter.)
  My plan is to electrify it, with a small generator mounted in the same area. Plan for propulsion is a small 4-6 horse (OB equivelant power) mounted on a regular OB bottem end so I can use the same mounting location. I sail far more than I motor, so range isn't top priority for me.

 That said, If I could pick up a good diesel generator at comparable cost I wouldn't hesitate to grab it, thougfh I would have to rethink the installation.

I think that the dangers of using gasoline in boats (and cars) can be overstated and other commonly accepted aspects of our transportation should be a greater concern than the choice of fuels.
