For a decent bracket. I'm talking about one with a BIG tub to support a large 4 stroke and swim platform. You will be real lucky to get just the bracket for $2K.
Going with a small tub bracket you will be doing yourself NO favor.
The boat will squat in the a$$ end more, scupper's could be underwater, etc,etc.
If the boat doesn't have hyd steering? It will need it. $1K. If it does have it, you will need bulkhead fitting and 2- 3ft hose's. Aprox $150.
Shift/ Throttle cables will need to be replaced with long one's.
It keep's going on the money end, but you get my point.
$2K for the job? Ain't gonn'a happen!
