Basically I like many of the Marinco products. However I just installed the 12v trolling connection in our boat and found two; what I consider critical, things missing. First; on their information in the blister pack and on their web site there is no listing of the amps the item is designed for and second the screws that hold the front cover slip on are made of steel!
Two critical things that for me sent one of their products from excellent to average. Marinco Grade C
