Do a google search for bayliner owners club. Go into the forum and post the question and you will get an immediate response from many knowledgable people in regards to that particular boat. Let them know the options included including drive and motor make and model
I seen your post at BOC. I hope you read my reply. If these do indeed have OMC stringers in them then run as fast as you can. Do not even take the boats for free unless for parts
Even if they had the OMC Cobra I would say skip the deal unless they drop the price an extreme amount.
