recently purchased a 74 mark twain V-sonic with the mercruiser 302 188hp. the boat looks to be in good shape but needs some interior work as it has been sitting for the past five years! the motor looks clean. the previos owner said i shouldn't have a problem with it starting once i tune it up,change the oil and other stuff. anything else i can do before i fire it up? are there any boat junkyards where i can go for parts? like interior and other misc parts? this is my first boat and any help would be appreciated!! ty
