I have a 36', 1979 Holiday Mansion houseboat with a fly bridge. It has twin 5.0 Volvo Penta AQ200D engines and 280 outdrives. It has plenty of power and handles great out in the open. I have separate throttle and shift controls. These work fine when there is plenty of time to move your hands around. The problem comes in, when the wind and tides are an issue and other boats and objects make maneuvering critical. I was wondering what is available as an upgrade so that the shift and throttles are combined to just two handles.
