Just thought some of you might like to see these numbers. Just took a ride past the Yentna Station Roadhouse with my new 22' Boulton Jet with 250hp diesel. I am no expert, but I thought this might spark a discussion. Let me know what you think.
Over 78 river miles
18.1 gallons used
27.6 mph avg speed
36.2 mph max speed
My public school math says 6.4 gal/hr...4.3 mi/gal...90gal tank gives me 390 mile range! We were not exactly easy on the throttle. Boat had three people plus goods for the Roadhouse and a friend's cabin.
