Have 2 of the blue 50 amp esc units in the Aziz. The remote switches on a lead are knackered due to the salt water. Takes quite a few on off movements to make a connection, going to solder the cables and do away with the switch. The unit is waterproof why don't they provide better quality switches . Don't see a problem as the battery is switched .

Having been running on salt water since 1982 I would recommend mounting the switches somewhere they wont get wet!
Or, a regular squirt with WD40 or a smudge of vaseline in the switch can stave off rust damage. Or extend the cables and fit a mini toggle switch with a rubber cover over it, available from RS Components and probably other places. Mainly, don't fit the switches on the deck, but under a hatch coaming or some such splashproof housing.

Hi The problem is it’s an AZIZ , OSV boat. Takes water in when sailing on open water , should fix the rear deck but that will not look right if I raise the hatch on the work deck. Next boat will be a trawler or lifeboat , they should sail well when the sea has a little swell. Fitted a pump but it’s just a car washer pump , takes a while to start because it’s not very good at self priming . Have removed the switches , opened them up for a look were well shot. All the other electrics are ok , positioned around the front superstructure hatch.

That is the alternative, remove as many points of failure as possible between the battery and the motor. This is the No1 reason I don't fit fuses, each fuse is three points of failure. The fuse itself (useful unless you have snagged some weed and are now stranded in the middle of the pond!), and both the 'in' and 'out' connection point, which will soon fail if it gets splashed. This is also why I am no fan of a big, inline main power switch.
The most reliable system I ever fitted was in a 'wet' boat and had no radio or main switches, no fuses (obviously), and relied on me unplugging the main battery to turn everything off. Worked every time!
