Question: What size is the hole that must be drilled to flush mount this?
Document: (By corroded I mean the brass (?) has green oxidizing all of it, one connector much worse than the other.) They're still making good contact, but I'm assuming that's going to change.They were flush mounted on horizontal deck.
This piece was the Perfect replacement part for my stern light outlet connection. Easy install and a nice sealed fit
This is a well made product and worked as I had hope. Item is as described and is of good quality.
This is a well designed connection and looks nice mounted. In this case it is used for a solar power connection. It would have received 5 stars except for the set screws which should have been hex to make it easier to tighten.
The quality is good. You have to buy your own stainless screws.
Only thing I'd love to see is some other options for a 3 prong..etc. Would be great for running a wire up my mast for the deck light and steaming light together.
May yours last forever...
I've used this in two places on our boat, one on top of the deck and another in the side of the seating in the cockpit. It works great in both locations and have not had a single issue with water getting in.
I replaced an older similar type deck mounted connector. This connector mounted quite easily and it appeared to be more resilent to the weather
I bought a 13 year old freshwater sailboat that used these connectors for the mast lights. They had corroded and were making intermittent contact. The rubber had hardened and wasn't pliable anymore, so it probably wasn't sealing anymore.I don't know if they were the original equipment with the boat, so I can't say for sure it took them 13 years to get to that state in the fresh water.
Answer: no
