Thanks for the input guys. So we are looking at roughly $900 in increased motor cost per year from 18 to 23.

Being close to sea level I don't need a 450. However, there is a used boat of interest with a 450 and I'm trying to estimate what they paid for the boat. The used boats I've been watching minus the G23's aren't moving. I'm starting to see some prices drop to what I'd expect folks paid just not on the boats on the top of my list.
