WVSA Series
240 – 1540 | 500 – 4,900 kW
Down-angle reverse-reduction gearboxes for fast vessels. Beveloid gears angle the output shaft 8–10° downward, lowering the power train and shrinking the engine room — with the high power-to-weight ratio and quiet running of the WVS series.
Lower the Power Train, Shrink the Engine Room
Built on the proven WVS platform, the WVSA down-angle gearbox angles the output shaft 8–10° downward with beveloid gears — freeing designers to install the engine horizontally while reducing overall engine room height for new builds.
High Power-to-Weight Ratio
A weight-optimised design delivers a power-speed ratio up to 2 kW/rpm, maximising output for minimum mass.
Space-Saving Down-Angle
The 8–10° down-angle lowers the power train and reduces engine-room height — crucial for new-build naval architecture.
Low Operating Noise
Optimal tooth-flank corrections, synchronised engagement, and resilient mounting absorb noise and vibration onboard.
Design Freedom
A wide reduction range of 1.5 to 4 and configurable shaft angles suit mega-yachts, patrol vessels, and crew boats alike.

Specifications
WVSA Down-Angle Reduction Gearbox
WVSA down-angle gearboxes deliver a power-speed ratio of up to 2 kW/rpmwith a reduction range of 1.5 to 4and an 8– 10° beveloid down-angle. Main dimensions (mm) are from the REINTJES WVSA 240– 1540 brochure for the 740, 940 and 1540 sizes — WVSA 240, 340 and 440 are available on request. Dimensions and dry weights are for the standard design and are not strictly binding (subject to change). Per-ratio ratings are application-specific; contact Karl Senner for a binding gearbox selection.

Where These Gearboxes Go to Work
Patrol craft, pilot boats, and fast motor yachts demand high power-to-weight and quiet running. REINTJES fast-vessel gearboxes deliver both — in compact configurations that save space in the engine room.
