Re: Volvo Penta mechanic at Lake Lanier??
We used First Mate Marine off Keiths Bridge Rd in Cumming. Luckily we never had any trouble with our Penta engine, but they always did our winter and summer-izations without any trouble and seemed to be fair on price.
We now have a new boat, so I haven't been back to First Mate in couple of years. Good Luck1
