I am considering putting a larger motor on my boat. The boat is a Nitro Z7, 18’ 8”, and is rated for a 200 HP. I presently have a 2009 Mercury 150 EFI (SN1B693339) on the boat. Boat and motor have both been garage kept since new, and are in near mint condition. Now the question, what would be a ballpark value of this motor and controls if I sold it to gather funds toward a new engine? I know this would depend on results from compression/leakdown/ and all other necessary testing that is appropriate prior to putting it up for sale. I am just in the information gathering mode at this point. Thanks
