Ummm... just one thing.
I started with cruisers and worked back to performance.
A skinny boat with twin I/Os simply can't do some of the tricks that fat twin IBs can do. The props are way farther back, closer together and you have no separate rudders. (required for the "sideways" move. sorry)
The experience you had with the last boat will help you in the long run, and you will get the hang of what you can and can't do with twin I/Os. But you will be disappointed if you expect to pull sideways off of a pier or turn 360 in one place.
Your new boat will turn on an axis that is forward of what an IB cruiser can do.
I'm guessing that you have counter-rotating drives on the new boat. You will find that one will "walk" one way, and the other will "walk" the other way in reverse. My bet is that you end up using one more to pull alongside with your SB, and the other to pull alongside with your port.
Now.... go buy some gold chains and some cool sunglasses.
You are a performance boater.
You will also need the theme from Miami Vice on MP3 so it doesn't skip.
