"Far" is probably not the right word.  Think run time.  I got it stuck in my mind that you are going with an old veedub engine and I'm too lazy to go back and look.  So now, a thought experiment:  Lets say we got 25 mpg and a roughly 250 mile range out of a 10 gallon tank at say 50 mph with our experimental bug.  Let's also say that 50 mph is it's best (most economical) cruising speed.  Looks like 5 hours before you have to break out the oars?

I have no clue what the most economic rpm will be for that engine, and that will heavily influence run time.  The prop will also have a huge effect. 

I actually envy you the experiments, living with you vicariously.  Good fun.
