1981 Volvo
I have a Bahama 30 with an MD7A, the same engine you have. After 25 years they get a little tired, if is used in salt water, you may have cooling problems. There are good posts on the sailnet Islander web site about this issue. Compression on a diesel is important, mine is getting low, so I will need to think about a valve job, or repower. They are good engines, but expensive to repair as the parts are mostly propritary.
