Thanks guys, new boat and I'm pretty disappointed in the performance and Parker for publishing the data they do. On their site, a 2520 XL is published at 30.5 mph at 4000 rpm and right at 46 at 5700 rpm.
2/3 tank of fuel, 1 person, bottom painted, perhaps 100 lbs of gear, on flat water 30 mph comes in at 4200-4300 rpm and I can just touch 40 mph at 5500 trimmed way up. For comparison, my bottom painted MV 2510 did 30 at 4000 rpm and topped out at 40 with the old OX66 225 though it did have 2* less dead rise.
I realize that any published number are basically not to exceed numbers, and I can understand some delta in performance, just not sure why their test boat did 30.5 at 4000
Rpm and mine does 27.5 at the same rpm.
End rant, I still like the boat...
