As to installation cost, because the unit bolts on externally, there is no cutting a large hole across the bow with all that entails, no glassing in a tunnel for the propellers, probably requiring several days out of the water.
Figured I could get by without one so never made a choice.
I'm a huge fan of thrusters. Even if I ordered a boat in the 35' range new, I'd get them. However, if I had a boat in that range or was buying a used boat in that range, then I would not go through what it takes in work or cost to add them.
