Talked to WM and the ducer only came with a one year warranty. Unfortunately for me I bought it one year and 3 months ago so I had to buy a new one. Except the new ones are 8 pin and I need a 6 pin and of course no has them$13 adapter in stock. Bought the extended plan this time. Also I will never use 5200 again for a transducer. There is not enough room in the bilge to comfortably work to get that nut off when it has 5200 at least a quarter inch above the hull as per the instructions which is how I installed it. It took some creative use of my truck jack and a huge wrench to budge the nut free. All told 3 hours to remove the nut and 30 minutes to pop it out of the bottom. 30 minutes later the whole was cleaned prepped and new ducer installed. Now I have to wait to get the 6-8 pin adapter.
