I have an 18 ft. 1983 Boston Whaler GTX I/O that Im trying to get a feel for its value. I cant find much online and I don't know much about I/Os nor do I have the money to do it right now need to get rid of 2 boats. Its has a Mericruiser 488 rated HP is 188. When I first got it I couldn't even find a pic online of another one. It needs a little work. The previous owner has never put it in the water or started it. They wanted to but never found the time etc. They said the owner before them said it just needed a battery. When I got it I was told it needed a battery and the owner had the carb out to have rebuilt, a 4 barrel Rochester, which I have. Its needs some hoses and some tlc from what I see but again I don't know much about sterndrives. If anyone had any input I greatly appreciate it
