Welcome to the site and congratulations on the new 275.
I have the same boat in a 2008 with an F350, no hardtop.
Slow speed maneuvering on this boat takes getting use to as it is a long boat to have a single on it. It backs to port like you would expect, very unresponsive. When backing into the slip you need to slide it and not try to power it. I have a port slip and leaned last year to trim the engine up to three or four bars when docking as it felt to me as though the stern was a little more responsive than with it trimmed full down. I also learned to use small bursts of forward to snap the bow to port when backing down into the slip and found myself 2' off of the finger.
In general the boat handles nicely and I have been very pleased with the F350 , the fly by wire controls and the boat and engine as a combination. Plenty of torque out of the hole or in rough water and more than enough speed at top end (about 45 MPH fully loaded). Cruse is at about 30 mph if I remember correctly and about 2.1 mpg. Forget the GW number of 2.4 or 2.5 MPG it is a fairytale. I have had the boat out in sloppy 6’ seas and she handled it like a champ.
Outside of the lower intake port of the engine being underwater all the time and a few very minor issues I have no problems to report after one full season and about 150 hours on the engine. My wife and I love the layout and are very happy with our purchase. If day boating doing a combo of finishing and playing are your thing I think you will be very happy with the 275.
