Re: [Electric Boats] Gas vs. Diesel

Mokai. YouTube has lots of videos...

Noisy, slow, and lots of vibration aren't advertised, but should be.

Sorry to get off the subject thread Myles...

I'll second that. My el cheapo gas generator will leak gasoline if I leave the fuel line open with the motor off. That's one of the reasons converting to CNG (search for earlier post) came to mind. Even keeping it on deck there are places where gas could theoretically get inside

I also had the joy of troubleshooting it this last weekend - motor on, but no electrons. Taking the generator side apart, looked for obvious corrosion (surprisingly little considering how many waves the little thing had taken in the face) - fully expecting to end up with lots of parts and still no sparks...but noticed the brush commutators looking a little dodgy. Took that apart, made sure the brushes were springy, and bingo - came back to life (and only 3 extra screws)

Arby - if you're going to mention jet-powered kayaks you must provide youtube links! Quit teasing!

Although my experience with a utility Honda engine in a jet powered kayak didn't lead to a sunburn, it was a close call when the side-draft carb flooded the "bilge" with a half a gallon of gasoline. The motor was not designed for maritime use, and I suspect 99% of all gasoline generators aren't either. Marine gasoline engines use down-draft carbs. At least with a diesel, the chance of a spill is just messy, not life-threatening. I'm currently re-powering my own 25' Skipjack, and will probably use a gasoline genset as I have a 100 gallon fuel tank. The genset will be Marine UL listed, and mounted fully enclosed with a explosive fume detector, not sitting on the bow dribbling fuel.

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.
