Up for bid is a Raymarine Raymarine ST4000+ Autopilot head. The listing includes the display and cover only. As you can see I powered this up, I don't have the rest of the system to test further. This was removed as part of a whole boat electronics upgrade. This unit was reported to be in working condition when removed. Unit presents well, but has on very small crack in the outer casing, This shouldn't impede function, but I'm mentioning it in the interest of full disclose (see last picture). Because I have no way to test this fully and I never personally used it I have listed it in this category.  Please take a look at my other listings for more marine electronics, as well as lots of other marine gear and quality items. I'm always updating my inventory, so save me as a seller to keep up to date with my offerings. Good Luck, Happy Bidding!!!
