Check inside your binnacle. Not sure about the Hunter Legend 40, but my 1994 Legend Hunter 40.5 was set up from the factory for a Raymarine Rotary Drive that can be bolted directly onto a bracket inside the binnacle and usew a chain drive directly to the wheel shaft. Much better than the wheel drive and more robust. Still uses the cables/chains that the wheel uses so maybe not as redundant as the linear drive but still a lot better than the wheel drive. Check out Rich Stidger's mods on the Hunter 40.5 mods page on this site. If you have the platform there it will be obvious (about 1 foot below where the wheel shaft extends to the front inside the binnacle). Pretty reasonable to install, but still expensive comparred to a wheel drive. best of luck and happy cruising.
