Congrats on your new boat!
We LOVE our 2007 Yamaha boat. Tons of room for a 23'er, lots of power and a great hole shot. We just got back from a week at Lake Cumberland with a group of 44 people. We logged over 170 miles on the water in 6 days, and never had one issue. Everyone who rode on our boat loved it. We pulled wakeboards, skis, and tubes with no issues. One of the best things was not having to worry about a propeller hanging off the back of the boat while all of the little kids jumped in the water.
Like RumDiet said, Jetboaters.net is a great resource for getting answers to any question you might have.
Enjoy your new boat!
