There was a bit of interest in specifications and performance for the new
Parker 34 with the twin F350s. This is what will be on the Yamaha site
soon:


The following performance data was provided by Yamaha.
Performance will vary depending on conditions and load.

1000 rpm, 6.8 mph, 2.9 gph, 2.37 mpg
1500 rpm, 8.2 mph, 5.1 gph, 1.61 mpg
2000 rpm, 9.7 mph, 9.1 gph, 1.07 mpg
2500 rpm, 12.0 mph, 12.8 gph, .93 mpg
3000 rpm, 19.5 mph, 18.1 gph, 1.08 mpg
3500 rpm, 27.3 mph, 22.9 gph, 1.19 mpg

Interestingly, 4000 rpm is the "cruise" mpg sweet spot for my little
Yamaha F150, too.


Here's a factory-supplied shot of the main cabin of the first production
boat:

Minimum speed is too fast for tuna.

Uh...that's not minimum speed...that's the speed at 1000 rpm. :)

The F350's have a trolling throttle controller, +/- 50 rpm increments
(600 - 1000 rpm range) via the Command Link System.

My F150 runs just fine at 600 rpm, and according to my gps, I can power
the boat forward in still water at under one mph if I want. I assume
most modern outboards can run real slow, except maybe some of the two
stroke engines.
