I know you may not be the owner of this boat anymore, but I am thinking of buying this from a dealer in Florida. It does not not appear to have been run much it still shows 250 hours.
Is there anything you are aware of mechanicle wrong with this boat? Did you flush the engine otherwise in salt water?
Anything else I should know?
I am grateful for any insight you would be willing to share.
