Many thanks for all the helpful comments. Especially the cautionary ones. I've been guilty over the years of not taking proper precautions, but I mostly do now days. Even though it's a bit of pain sometimes.
I appreciate the concerns and am happy to report that the owner of the boat decided to keep it when I told him it was not seaworthy. It was one of those one piece shallow little boats that is prob rated for what? 10 HP? Not only was the 25 pushing in the transom, but the boat had rammed something hard enough to crunch the bow and buckle the front bench.
Guy says, Sounds like you really don't want the boat. I said not really. Well help me push it off then and I'll throw it on my burn pile! LOL
So anyhow I got me a really promising looking rude 25, two tanks, boat cover and an asst of other goodies and NO turd boat to pay to get rid of! Now just got to figure out what to do with a pretty nice tilt trailer that has no docs or serial no. plate on it. Since it's out of state it won't be easy, maybe not possible, to title it. So it may just be going to the scrap yard, but at least I won't have to pay to get rid of it.
