I agree with Dick 150% You should have any Baha Surveyed before you purchase it. And I own one! LOL! Please PM me with any questions as I purchased an 89 that was "surveyed" and I lost my shirt on the deal. I now own a 92 28 Baha Fisherman. As far as a Baha goes if it is solid you will not find a better Hull for rough water period. And I am sure I will take flack for that comment! LOL! My guess would be if it hasnt had bulkheads and stringers done in the last 5 years its going to need them as well as a transom. I am not saying that is the specific boat you are looking at I am just saying what I know on pre 92 Baha's. Let me just say again That I love Baha's they are the best rough water boat, but you gotta know what you are purchasing. As for the 351 Clevelands they are bullet proof. It probably also had Borg-Warner transmissions which are also bullet proof.
Please feel free to PM me if you have any questions.
P.S. Older sport crafts also have Bulkhead and stringer issues. But then again pre 90 Tiara's also have bulkhead rot so it is the nature of Beast!!!!!!!!!
