I recently purchased the above 2009 boat with a 40MP Mercury 4 stroke. I was surprised to learn that I could only achieve top speed of 22mph @ 5800rpm with full tank of gas and 2 normal size adults on board. Boat felt as if it really never got out of the water. This is my first deep hull so maybe this is normal......much different than other pleasure crafts I have owned.......any thoughts would be helpful.....thanks.
