Big Dog went through a full re-power in 2018 at Bayliss Boatyard and received new MAN i6 800 hp motors, new Phasor 20 kW and a full paint job in the engine room. With her new motors she cruises effortlessly at 29 knots while only burning 60 GPH and 34 knots at WOT. She has had a full electronics upgrade in 2017 to include a Garmin package, FLIR camera and more. This classic is a fish raising machine and a proven money winner. With added fuel to 1100 gallons, her range is plentiful to fish anywhere you desire.
