I agree salty, i had a mariner unit that i had bought on ebay,i ended up trading it away to a friend who needed it more before i got to use it, it looked well made and i like the concept
. I have an old Famet like Sara mentioned on one of my boats and it too works great, it had a couple of bent foil sections when i bought the boat(from the mast
falling down) but to my amazement i found a guy who had a lot of spare parts
in his garage,i like the simplicity and it works as well as any i have used.
