I am thinking about buying a 1969 Highliner 21 Sportsman with the original 289/Volvo outdrive. The outdrive has a Holman Moody tag on it. The boat has been restored and is perfect. The boat has always been in freshwater and everything currently works well. My question is: are these old drives good and reliable? Can I still get parts for them? What should I look for? Should I run away?<br />Thanks,<br />John
