you have the 150hp on this hull, what kind of performance do you get?
Regards, jdr2
On a side note, I curretly own a 30' Pursuit, a 18.5 Edgwater and a 18' action craft. I have also owned several other bigger power and sail boats.
I have about 150 or so hours, but no fuel managment so can only estimate usage. The Grady site does have good charts on speeds, gph and mpg, on the various engine sizes.
I do know that $100 worth of fuel is good for a couple of weekends of playing on the water. Fuel costs are the least of my worries. We do a few runs a year to Catalina Island, it's 28 miles across the San Pedro Channel here on the west coast. A round trip and some trolling and puttering around fishing will burn about a third of a tank, or about 25 gallons. So we get at least 3mpg, probably a little better. The Grady report shows 3.84 at cruise, but we all know it's darn near impossible to duplicate. They show 4mpg on the 209 with the F150, that's a breath of fresh air compared to twin HPDI 200's on a 26 footer!!
I'm more happy with the performance now that I have used the boat for a couple of seasons. It's not a hot rod, but in most conditions you wouldn't want to carry any more speed anyway. In flat conditions a 200 would be nice, or if you plan to do a lot of water sports, boards, skiing, etc.
Cruise is about 27 at 42-4300rpm, WOT about 37-38, 2-3 people and half a tank. If I need to make speed and the water conditions permit it, I'll run at 45-4800 for about 30mph.
I run a 15x15 prop, the Grady test boat gets a little more speed with a 13-3/4X17. I gladly give up the top mph or two for a better hole-shot and wave climbing ability. She runs great in a sea. I have also not had any trouble getting on plane with a boat-load, 5-6 people and gear, so the 150 seems like a real economical package for the 20' hull.
Compare the performance data on the factory site. With the bigger motor you do pick up about 3-4mph on top end, but suffer a bit on fuel.
