We recently bought a 2012 Freedom 225 with a Yamaha F250XCA. We have the 15.5X17 Yamaha SWSII SDS prop which originally came with the boat. The best fuel economy I have gotten so far, is between 3.2 and 3.3 mpg at 3500 rpm which runs the boat between 26 and 27 mph GPS. The fuel tank was full, 2 adults were on board and the bimini top was up. I know these results were pretty good, but I was trying to match the performance bulletin on Grady's web site which shows 3.6 mpg at that speed. We just bought the boat used (10 months old with 110 hours on the engine). The 100 hour service was just performed by the dealer.
My question is which engine trim/trim tab combinations yield the best economy? Also, any other suggestions on how to best operate our new (to us) boat will be appreciated.
Thanks,
Vic
