21580932 Steering Gear | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta planetary helm gear for tilt mount, the standard feedback version, weighing 1.978 kg and listed for 7 applications across the D-series and VMM ranges. It uses the three satellite planetary gear design for a good reduction ratio with minimum effort and less torque feedback than a single pinion helm. The tilt mechanism is not included and has to be ordered separately - 22299003 is that mechanism, giving five locking positions across a 48 degree range.
