There was another experience that I did not mention in the original post. There was a young couple and two 10 and 11 year old ( or so ) children that launched an old boat, first time they had done it. It was a 17.5 footer, 4.3 L Cobra out drive. Anyway, they launched, they did well, and I took the rope and moved the boat out of the launch area so others could continue launching. When I pulled on the boat, I was really surprised how difficult is was to move, I mean it was a strain.....LOL. Anyway, thought well, this is one well built boat. The man comes back after parking his truck, can't start the boat. He pulls the engine cover to have a look, and you could hear the water running in the boat, already had 8 or 10 inches of water in it. He turned on the bilge pump, thankfully it worked, water started going away. It was at that point I realized a couple of things....1, the boat was probably very water logged, 2, at the rate the water was coming in, and as mentioned, you could hear it, in reality the boat was probably unsafe. I told him he may have a leaking bellows of some sort. He thanked me, got it started with a little help from me, then went on his way. I just wasn't sure what to say to him. When I saw him drive away with his wife and little kids, tho I didn't know them, I felt a bit of worry, and maybe a little sadness. Again, I really enjoyed helping all the folks, but I just didn't know what to say to this man....Looking back, I'm thinking I might should have told him that his boat was unsafe! I think if I ever experience this again, I might pull the man off to the side and kindly mention that the boat may not be safe to operate. I guess it was none of my business.....I just don't know.
