1Introduction


Introduction


SailDrives (SD) offer a highly efficient and comfortable Z-shape sailboat propulsion system for motoring while not under sail as alternative to standard shaftline solution.

ZF Marine has long standing experience with this type of propulsion system and its well-recognized advantages of excellent hydrodynamic efficiency and ease of installation that makes the saildrive the preferred solution, >90%, in the sailboat market.

Previous ZF SD portfolio covered engines up to 80HP (SD10 and SD12, ZF branded, or equivalent that ZF produces for main engine manufacturers)

Saildrive ZF SD15


Key Product data:

• 170Hp@3500 (360Nm) rpm Saildrive transmission in Pleasure Duty (private)

• 110Hp@3200 (250Nm) rpm Saildrive transmission in Light Duty (charter/rental)

• Innovative technology: SD15 includes unique features like hydraulic clutches, integrated output shaft brake and oil cooling circuit trough the leg

• Market price is competitive with the overall market price of the shaft line alternative (prop shaft, struts, hull interface, increased labor time,...)

• Launched mid 2020, more than 70 units already in the field

SD15 extended legSD15 standard SD15 «C» configuration


Main technical features: Hydraulic clutches


Double hydraulically actuated multi-disc wetclutch to bring the best shifting performance in this power range


Main technical features: Emergency procedure


Clutches can be manually engaged in case of electric/harness failure failure


Main technical features: Oil change in the water


Oil can be changed with the boat in the water from the top of the drive (during the season)..

… or from the bottom of the leg for allowing a complete and more clean oil change


Main technical features: anodes and output shaft seal


The anodes can be replaced without removing the propeller

The position of the output shaft seal can be moved prolonging the output shaft life


Main technical features: Oil cooling through leg

Oil circuit force the oil circulation through the leg allowing natural heat exchange with the sea water

Oil cooler not needed in most of the applications



Main technical features: Integrated negative brake

When the diesel engine is off, the brake is keeping the output shaft blocked. This allow the foldable/feathering propeller to properly close and stay closed during sailing



3Saildrive vs Shaftline


Saildrive versus shaft


• More compact for better engine room location/space

• No engine inclination

• More efficient (prop shaft @ 0°)

• More distance from the propeller to the rudder (less vibration, more comfort)

• Allows modern flat-body hull design (form stability)

• Propeller walk reduced

• C-configuration for additional weight balancing and space saving (especially for catamaran applications)


Saildrive versus shaft


Transmission ZF 25 A ZF SD 15

Shaft Integrated

Shaft strut Not necessary

Shaft brake Integrated

Through hull interface Not necessary

Water intake Integrated

Propulsion installation/alignment

GRP (through hull, strut support, etc)

• Integrated water intake

• Integrated shaft brake

• More easy to install in the production line, fixed installation time (no adjustments / no variability)

• Competitive final cost


4Application range and examples


Example of engine matching – Pleasure duty



New built boat ZF SD15 power range is perfect fit for new built sailboats and catamarans from 50’ to 80’

Repowered boat ZF SD15 can be used for repowering a boat equipped with a smaller saildrive with minor hull/engine room

modification but can also be considered for repowering a shaftline with some additional hull/engine room rework
