🔧 Product Description

Genuine Volvo Penta lower gear from the Marine Propulsion group, weighing 34.473 kg and listed for one SP application. No ratio is published against it, unlike the DPX gears in this range which carry 1.59:1, 1.68:1 and 1.78:1 markings, so the SP drive's own listing is the only way to confirm it.

🚤 Compatibility

Typically suits:

  • Volvo Penta SP-E
  • Engine Family: SP

⚙️ Key Features

  • 34.473 kg
  • One published SP application
  • No ratio marking published — confirm against the drive
  • Marine Propulsion group

🔌 Function

Forms the lower gear of the SP drive's reduction, meshing with its partner to carry the drive from the input shaft down to the propeller shaft.

⚠️ Common Signs of Failure

  • Whine or growl under load, changing with the gear selected
  • Teeth found pitted, spalled or chipped
  • Metal glitter or bright flakes on the drain plug magnet
  • Backlash or roughness felt at the propeller shaft
  • Milky drive oil showing water ingress

🛠️ Service Notes

  • Gears are matched to their partner and a shim setting — renew as a set and shim the mesh to specification
  • At 34 kg this needs proper lifting and support, both on the bench and in transit
  • SP gear housing 3860244 is the casting these gears sit in

📦 Condition

  • Genuine Volvo Penta part
  • Brand new
  • Supplied in original or equivalent packaging
