My father got a 1986 Bayliner Contessa. It has a Volvo Penta sterndrive and motor. It is a AQ260A 350 V8 enngine and he needs to know what sterndrive is on that engine for that year. I don't know anything about boats and told him I would try and see if anyone out there could answer his question or point me in the correct direction. It took me awhile to figure out how to post on this forum and what topic to choose. I hope I am conveying his question correct. Thanks for any help you can give me.
