Boat Performance Update

Two guys, full fuel load (100 gallons), cooler, ice, rods, and the usual junk: 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 6 gph. UPDATE: This past weekend out on the Patuxent River with my wife aboard and with a buddy aboard, too, with 80 gallons of fuel in the tank and two coolers, plus the bimini top up, and the usual assortment of stuff you have to have with a female aboard, including a folding lounge chair (!): We got 40+ mph at 5900 rpm in flat water. The acceleration is outstanding with the 15-1/4 x 15 prop. The boat jumps right up on plane when you firewall the throttle and you can almost immediately pull back for a smooth cruise. Nice flat wake, too, and with the almost flat through hull transducer, no little rooster tail off the transom. I rarely will have more than two or three other people on this boat, so I am well-pleased with the WOT figures, since with the damned chop on the Bay much of time time, running at 25 mph is much more likely, and even more likely many days, running in the low 20s. The fuel burn at cruise is in the low 6 gph range. When I was contemplating this new boat, I considered for a while going with an F200. I'm glad I didn't...not for my usage on Chesapeake Bay...the ideal match is the F150. _________________ That is great news. thanks for the update \ Would a silver prop perform better? No, the black prop delivers much better performance. |
