I have the chance to buy a 1976 Coronet Seafarer with Volvo Penta AQ165 engines. The boat has not been in the water since 2007 but has been started up on a regular bases. Is there anything I should be looking at in regards to the engines, ie, seals, etc. I have never owned a boat before but looking for something my wife can go out for a weekend and do some diving, this boat fits the bill. Any advice would be appreciated
