Funny you should mention that. I was looking this morning at Side-Power bow thrusters for my imaginary boat (imaginary boats are substantially cheaper but require just as much thought).
What struck me as odd was the similar price in the thrusters in the different tunnel sizes. These are for mid range thrust 24 volt not variable speed. My guess is you will need a tunnel size of 8.5", 10", or 11.8".
8.5" with 330 thrust is $5.7k
10" with 440 thrust is $8.5k
11.8" with 550 thrust is $8.6k
Now I understand there is more to the thruster than the cost of the unit. But to my way of thinking, unless you let someone BS you, the cost of installation (which is often the most expensive part) shouldn't be hugely different. Cutting the hole and glassing in the tube, shouldn't be hugely different between an 8.5" tube and an 11.8" tube.
IMO, get the biggest tube size that will fit your boat. Within reason, bigger diameter propellers give better push with less slippage. Secondly, I've never met a person who said their thruster was too big and too powerful. There are plenty of people who have ones that under perform.
