The Volvo MD2030 engines and 130-S saildrives were getting too expensive to maintain. The exhaust manifold / heat exchanger housing on the starboard side had already been replaced after a hole appeared in the casting. Both engines were leaking oil. One of the saildrives had saltwater intrusion after only 20 hours of operation post-seal replacement, indicating a defect in the output shaft. A new Volvo saildrive was going to cost almost as much as a new Yanmar engine and saildrive combined, so the decision was made to repower both sides with Yanmar 3YM30AE engines and SD-25 saildrives.
