how much should this job cost in Memphis Tn by an outboard motor mechanic? just a rough range.. the part is about 50.00 at this looks too difficult for me or at least too time consuming.. thanks
This is about a 2 hour job at the labor rate in your area. I'm in the Florida keys and the labor rate down here is $100.00 an hour. So your job down here would be $250.00.
