Quick fix for a small water leak in a Mariner 4.
I've noticed a bit of water in the bottom of my Mariner 4 the past couple of floats, when flipping it over and carrying it on my back up the boat ramps. Not much, but it seemed like more than was coming from my soggy shoes.
I aired it up and set it on the rails of my porch and poured a tote full of water in it. Pretty quickly I found a fairly small (less than 1/32-1/64 of an inch) hole in the bottom of my boat.
The way my boat is made, the bottom of the boat doesn't inflate. It's just like a thick tarp material with a long tube that inflates down the middle. The hard floor sits on top of that. It's surprisingly sturdy. But what that amounts to is there is an empty space below the floorboard. It's not inflated. It's just a thin empty space.
But after 15 or so miles down the river there's about a pitcher of water down there. It's not a huge deal, it never even comes over the floorboards. But I'd just like to patch it up.
I'm floating early tomorrow morning. Any ideas on something I could pick up at walmart, on the way to the river, and slap on it? It's in a place I can see and easily get to. I was thinking of one of those little, round, bike tire patches, but I read several google reviews suggesting that they don't stick to raft pvc like mine. I've also got plenty of duck tape, but... does that really work?
Any suggestions from the pros?
