22227295 Volvo Penta Gear Housing Complete Lower Unit DPS-D1 2.32 | Genuine Used Part

🔧 Product Description

Genuine Volvo Penta DPS DuoProp Complete Lower Gear Housing - Part Number: 22227295

A genuine Volvo Penta complete lower gear housing for DPS-B1, DPS-D and DPS-D1 DuoProp sterndrives.

This unit was supplied as a DPS-D1 2.32:1 application. The lower gear housing itself is shared across 1.95:1, 2.14:1 and 2.32:1 drive configurations, with the final overall reduction determined by the matched upper gear housing.

The assembly uses two counter-rotating propeller shafts to improve acceleration, low-speed handling, directional stability and propeller grip.

🔌 Function

The lower gear housing transfers power from the vertical driveshaft through the bevel gears to two counter-rotating propeller shafts. The opposing propeller rotation reduces steering torque and improves thrust, manoeuvrability and acceleration.

• Milky or contaminated gear oil from water intrusion
• Gear or bearing noise under load
• Propeller shafts have excessive movement or runout
• Oil leakage around the propeller-shaft seals
• Damaged skeg, cavitation plate or gear-housing casting
