Hi I'm a newbee to GW. former Carver cabin cruiser. just downsized to 1999, GW 272 Sailfish in late Oct and on the Hard since Nov, launching in two weeks. It was boathouse kept on chesapeake. very good condition. I'm currently looking to replace my Raymarine and Furano electronics with Garmin system. due to size constraints I seem to have to go with Garmin 943 instead of Garmin 8600 series. electronics guy I trust will be installing etc. Is there anything I need to know as the new guy about these Sailfish 272 boats. thanks
