Local angle. St. Catharines
We see St. Catharines boats from three kinds of water: Lake Ontario out of Port Dalhousie, the Welland Canal, and Lake Erie by trailer. The work runs from cooling and fuel-system diagnostics to charging faults, lower units and fiberglass repair. We keep parts in stock, write the estimate before the job, and log every repair so the boat's history follows it year to year.
