30 amp plug

William.
Hard to tell from your pic but it looks like your connection is the same as mine was on my Pursuit, low on the deck and getting washed in salt water on rough days and soaked when it rained, and the cables all over the deck.

Another option if it works for you would be to shift it up under the gunnel where it stays dry, on mine the cable actually dropped down to the original location so I didnt have to lengthen the wires. I put a plate over the original location.

I used the old 30 amp marinco plug wire that was burnt at the plug.left the yellow outer on and was able to snake it plug to circuit breaker.i assume this wire is suitable.power is working fine so far

Confusing as written by I am interpreting this that you cut the head off of your shore power cord and wired the cord directly to your onboard shore power main breaker, thus eliminating the twist connect in the cockpit and eliminating the bad run of wiring from the twist connect to the onboard breaker. So I guess access wasn’t too bad if you got that done…

I caught the same issue on mine this summer

I had exactly the same situation, burnt plug, the odd breaker popping for no reason.

When I took out my receptacle from its spot under the gunwale I found the strain relief arm which held the wires secure from movement had frayed through the hot wire which was corroding way from salt air.

I got to it just in time before a short occurred and pulled a new run of triplex under the better safe than sorry approach to boat maintenance.

Fireisland makes a good observation, that looks like regular ol un-tinned building wire and ideally you should be using tinned wire designed for marine applications.

However, it doesn’t look exceedingly corroded where you cut it back, so you might be able to get a bit more life out of it. Follow corey’s advice and crimp some pigtails on their, use some corrosion x and shrink wrap the connection. If you do all of that it should get you by for a while.

Next time you have a little extra time and money you really should replace with tinned wire. At the very least you need to inspect your wiring for corrosion. If its all raw copper building wire, it needs to be very protected by copious amounts of grease, corrosion x, or something to provide even a modest service life in a marine application. Keep an eye on it, bad electrical connections can be dangerous.

I would remove the wire completely and replace with tinned copper. That wire does not look right.
