Can some one tell me how to detect a problem child in regards to used boats. I finally found a boat I have been wanting and it was within the price range I could afford. All I asked was a solid floor, a solid transon and for the boat to crank before I drive 5-hours 1- way to get it. Thats not asking too much is it. What I got was a solid floor on the outside, come to find out after looking into a service port that the floor is like kindling, the stringers are rotted and the built in under the floor gas tank leaks. WHoops. I found that out first day in the water after I filled it up went to leave my fishing hole and had a 1/2 tank, I only drove it about 10-minutes and I just put 10 gallons in a 30+ gallon tank. Looked in the service port and guess what, theres my gas. I took it back to the factory today for a total rebuild from the stringers up. Looking at about 3 grand. This boat totally fooled me, Chicken one day feathers the next. To save some tyoing for some one with the answers here is what I did. I got in the boat, stood on 1-leg and pushed down all over the floor looking for a soft spot. I raised the motor and pushed down on it looking for flex in the transon, it looked and felt good It cranked right up in the driveway but that does not mean much until it is put under load in the water. Under the calon it looks brand new, not even wear on the flywheel, the bolts did not look like they had been cracked, the freeze plugs looked like a new nickel. The hour meter said 420 hours and I had no reason to believe otherwise. Gave it a visual once over under neath, looked good, No transom cracks in the gellcoat. All the intrusions like transducers were tight and caulked. I do not know what else to do yet I still got a big piece of CRAP until I get it fixed. I thought I had a gem as overall it looked like it spent its like under cover and noty in the weather. By the way the service port was under the console, a place I did not bother looking as it was covered and under cover.
