I am looking to buy a 1988 campion center counsel boat with a Merc 115 two stroke. It has a merc 9.9 four stroke kicker. He is asking $4400. Is this a good price? What questions should I ask. Should I trial it on open water before I buy it? It includes a trailer. Please help me out with this purchase. Thank you. Any issues with the 115 Merc 2 stroke?
