The beautiful simplicity of Yanmar Saildrives makes it the sensible choice for numerous types of boats. With no problems from leakage, the Saildrive has truly earned its name as a "Safedrive" system. Its dual diaphragm design virtually eliminates leaks. The design also eliminates shaft vibrations as well as noise, alignment and stuffing box problems. The logical power to prop direct drive combines all the advantages of the outdrive-inboard systems and has now been well accepted in boating circles.
