80A Alternator Once an option, and now standard, it helps deliver maximum power for the cruising boater’s needs.
Saildrive Option A popular feature for those interested in reducing drag and increasing performance.
Convenient Service Points Makes it easy to perform routine maintenance or handle unexpected repairs.
Belt safety guard provides complete protection from belts and moving components
Seawater drain valves make it easy to winterize or drain water for maintenance operations
High-quality two-part urethane paint protects surfaces from rust
Legendary Reliability. Compact. Light Weight.Yanmar engines are designed for high performance and maximum engine life.
Tested under the most extreme conditions, you can always count on them to deliver
the power you need day in and day out, year after year. It’s simply the best power
package available for new vessels and re-power applications.
