Hello HankEthanol do not explode like gasoline. It will burn but do not cause a burst explosion like gasoline. It is safer and if there is an accident and it spill over the enviroment, you get some drunk fishes but nothing serious, after a hangover they will be fine.  
As far as I know in some states in the US is possible also to destill your own ethanol for fuel, of course you must get the permit. 
Is a ideaBest wishesJuergen

 Juergen,That is interesting, what makes Ethanol safer?  does it have a lower flash point?  No worries with the passengers drinking the fuel, I will post a sign that says" if you drink the fuel you have to swim home"  ;-)Hank

Hi Hank,An idea is to convert the motor to ethanol, it looses 10% power, but ethanol is saver than gasoline. The greatest problem is to avoid that the passengers drink the fuel :-).Best wishesJuergen

 Hi All,My diesel engine did not work out in the end, and 6 hp I suspect is a bit skinny.   I do have a beautiful 15 hp 4 stroke Honda outboard that has been converted to run a hydraulic pump inboard.  I converted it many years ago to power my sternwheeler but ended up with an antique engine. The engine is stripped down to a bare engine with external water pump and internal oil cooler.  The problem is, it is a gas engine, and that is a big NO NO or is it?   If the fuel supply is outside the hull and the engine is run out of fuel before a dive, then there is no fuel at all inside the sub while it dives.  An engine compartment blower fan can constantly circulate air through a duct to the outside of the sub.  I know as a rule it is considered a bad idea but with careful   installation it could be a very nice drive system.  This would be much quieter and smoother than a diesel engine.  The Honda would be very easy to remove from the escape pod if I need to escape.  The Honda 4 stroke is as reliable as even a Yanmar diesel.   I was bragging to a Honda mechanic one time that the Honda starts with two pulls in the spring.  He said it must need a tune up LOL  it should start in one pull.  Hank_______________________________________________
