It was too rough on the Bay Saturday for me to want to extend the
"testing" to the higher RPM ranges, but I did note that the apparent
sweet spot for my little Parker and its Yamaha F150 is 4000 RPM. At
that engine speed, with three guys aboard, plus 75 gallons of fuel
(3/4 tank), fishing gear, three batteries, cooler full of ice, et
cetera, the GPS and the boat speedo agreed we were doing 27 mph and
the fuel management meter said we were getting precisely 4.5 mpg.

I don't know whether that is good, bad, or indifferent; it just is.

On a different day but with a similar load, we saw 41+ mph at 6000
rpm. I don't recall either the the *exact* gph or mpg at that speed,
but it was typical for a 150 hp engine...using the one gph per 10 hp
"formula."
There's really no need to run at that speed, so I rarely do.

My Parker is relatively heavy for its length (2850 pounds, sans
engine, fuel and gear), and has 21 degrees of deadrise at the transom,
so comparisons with lighter boats with flatter bottoms aren't too
relevant.

Ahhh, 3 on board. A stooges reunion perhaps?

*Three* batteries on a small CC without a trolling motor? WTF?

Wide open it guzzles 14.7 gph x $4.5/gallon at the marina = $66/hour

I wouldn't run it wide open, either...(c;


Saw another twin-engined high-speed center console for sale at the
marina Sunday...500 horsepower. Crikey.

They are dime a dozen here in Florida, almost standard equipment for
serious open boat fishing. There are quite a few triples running
around also, and even a few quads. One of the local quads is run by
US Customs and Border Patrol - our tax payer dollars at work. :-)

Why is the counter-rotating prop on the outside rather than the middle?
For docking? I don't see the advantage.

Electric beer cooling? Actually that wouldn't take that much juice.
My guess is that it did have a trolling motor.

Nope, no trolling motor. Never had one. The boat came with *two*
batteries, Richard, and I simply added a third, which I put inside the
center console, along with a switch or two.
