I finally had some time today to mess around with the boat, complete the break-in cycle, and see what the boat will do.
Parker equipped my F150 with a 15-1/4 x 15 three bladed black stainless steel prop. Parker had been using props with more pitch and less diameter, and apparently mine is one of the first with the smaller pitch. I called the factory on this and was told the lower pitch prop helped the engine rev up to 6000 rpm, and also helped with acceleration.
Well...the factory was right.
Two guys, full fuel load (100 gallons), cooler, ice, rods, and the usual junk, and without trying, I got 6000 rpm and 40 mph on both the GPS and built in Yamaha speedo. I think there is a little more if I play with trim.
4000 rpm delivered 25+ mph, and 4500 produced just about 30 mph. I "cruise" at 25 or so, and with a little trim fiddle, I was able to achieve this with 3900 rpm, and about 5.6 gph. Su-weeeet.
Had the depth finder hooked up to the GPS, and I like the outcome...got a nice big depth indicator on the lower left of the GARMIN 4208.
This is one sweet boat. Heavy enough to smash down waves, dry-riding and for a 21-footer, plenty of walk-around room. Two outboard boats ago, I owned a nice 19-footer CC, but it was much lighter than this new Parker, and it simply did not ride as well.
