GL: Hyper Mileing - Twin Engines

In order to actually achieve real savings, you need to consider the
additional drag your prop is making in the water. A wind-milling prop
will actually create more drag than one that is stopped, as all sailboat
racers commonly know. A folding prop is the best for this application.
So in addition to changing the balance of how your boat runs, you are
creating more drag and using more energy (than normal) from the single
engine you run.

Improving fuel economy with twins is a great goal!  I thought I'd try  
it.

So, I checked the transmission manual. A "trailing on prop" is OK with  
my velvet drive.

In the Erie Canal, I slowed one engine gradually,  then stopped it.
