V: You probably had the old style that didn't have the rectangular flange on top to prevent twisting the receptacle with the plug which twists the wires and pulls them loose and together. You can't do that with the new ones and they also make a 6 gauge adapter.The Marinco plugs are OK in the heavier versions, but the 12vbp is only rated for 8 gauge wire. I actually had a small fire using one of these plugs years ago. It's what got me looking at Battery Tender.
The Marinco receptacle is designed for water to drain through if it should get in there. The cap is good for rain or splash, but a pressure washer will knock it out of the hole. The O-ring in the plug seals it off when its plugged in.Ok sounds like the marineco is a good choice. I just worry about water getting and stiting in the plug from rain or washing the boat. Is the rubber cap a pretty watertight seal? If so it sounds like it's the plug I need
Chris, this was rigged at Master Repair in Stuart, Fl. It's where I have taken every skiff I have owned for the last 20 years for TM rigging. You would have to ask Mike the owner that question.A very clean installation, love the battery box. A matching plug for your charger is an idea I will borrow. Why did you bring the negative wire to the block that the breaker is on?
