This reminds me of a time when i was really young. My family rented a boat and out in the middle of the ocean, we noticed the block had a slight crack in it and leaking oil. The only thing we had was duct tape. It got us back without leeking all the oil out of the block and the motor never overheated. Duct tape is not the same nowadays... Glad my dad was observent cause that could have been really, really bad. He noticed a tiny piece of smoke whisp by. When i say tiny, he was the only one to see it. Back then ppl dind't have cell phones, gps, or on star!
