4JH3CE1 Saildrive
More and more boat owners are turning to Saildrive power as the smart alternative to the problems of conventional stern tube shaft drives. The beautiful simplicity of this compact drive system makes it the sensible choice for numerous types of boats. Not only is reliability a big element in these designs but also stability, as they eliminate shaft vibrations, 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. The saildrive has been found to improve boat balance, give more maneuverability and better thrust.

Driven by the famous Yanmar diesels, these Saildrives put a lot of dependable power in the right place in a boat.

Easily installed with a toughened, thru-hull fitting, the new SD40-4T drive unit smoothly takes the rugged power of the JH diesels, which are now expanded up to 75hp.
