If using 100 HP takes 7 gal/hr, then 0.7 gal/hr means you throttle
down to 10 HP tops. Nothing magic there. And yes I know, it is
pleasant to dream that if you held your mouth just right, you could be
at the helm of a mighty sea boat again! My dreams tend to focus on
airplanes these days - the only toy I do not presently own but do
covet.

Had one of those too. Sold it at a low (and broke) point in my life.
Starduster II, a lovely biplane, 190 HP, CS prop. Wish I still had it but...
It's still around the area and I could have it I really wanted it but... at
this time in my life, the annual meds. are a concern.

Good luck. Get one if you can, you (and your kids) will never regret
it. You can always sell an airplane. Not so a boat.
