2003 Parker 2520XL
Yamaha 225 four stroke
About 32' overall (pulpit and transom bracket)
About 6500 pounds with engine, half tank of fuel, stuff
39+ mph at 6000 rpm, WOT 20 gph
24-25 mph at 4100-4300 rpm, 10 gph

Because of the incessant hard chop on Chesapeake Bay, I usually run at
20-22 knots, keeping gph under 10. I watch the fuel flow meter more than
anything else.

This is an educated guess- could be inaccurate, but after several outings
and refilling at the same gas station to a full tank after every outing, it
seems to be about right. I'm using the Hour meter on my electronic compass,
since the engine doesn't have one. The stated GPH rating for this
boat/engine/outdrive/prop combo is a little over 7 GPH at WOT, mine may be
better because I dont reach the 5100 RPM max engine speed due to my
over-pitched prop. Also, the StingRay hydrofoil supposedly improves fuel
economy 10% to 50%.

We skied/tubed for about 2.5 hours Sunday, and puttered around for about 2
more, on a calm lake, and burned less than 14 gallons. 3 adults and 1 dog
plus equipment. I'm not complaining at all...

There is one Volvo AQ131A-powered Glastron on our lake that is really
good on gas too (and quiet!). I just didn't realize they were THAT good!
