Key Advantages

Lightweight, Fast-Shifting, and Quiet

Aluminium-housed and weight-optimized, the WVS series is built for fast-vessel propulsion where every kilogram and decibel counts — from patrol boats to luxury yachts.

High Power-to-Weight Ratio

Aluminium alloy housing and case-hardened gears deliver maximum power for minimum weight, ideal for performance vessels.

Compact Dimensions

A tight footprint fits constrained engine rooms typical of fast craft, planing vessels, and yacht installations.

Finely Tuned Shifting

The "Fast Clutch" system on WVS 234–930 provides smooth, controlled engagement under demanding maneuvering.

Low Operating Noise

Helical, tooth-flank-ground gears and resilient mounting options keep onboard noise levels low for crew and guest comfort.

WVS Reverse-Reduction Gearbox

Use the selector above to switch views. Power Ratings show kW/rpm for each reduction ratio per the REINTJES Product Guide 2026 across Medium, Light and Pleasure duty (lighter duty cycles permit higher ratings). Main Dimensions give all gearbox dimensions in millimetres for the standard (input/output on opposite sides) and U-Drive (same side) configurations; weight columns list the WVS and the WLS counter-rotation and identical-rotation versions. Dimensions and dry weights are for the standard design and are not strictly binding (subject to change). Bold ratios are standard; additional ratios, custom ratios and input speed variations are available on request.
