Hi all. I need to replace the 12 hp farymann that is currently in my 29 foot Cal. I would like to get something used as I definitely Cannot afford to buy something new. Any suggestions on what type of engine would be a good fit. I want something with easily attainable parts, as this was the issue with the farymann. Volvo? Yanmar? Universal?
