Typically suits:

  

• Engine / Drive models:

• DPS

• DPS-A

• DPS-A OXi with straight propeller splines where Type I is approved

  

• Important Fitment Notes:

• Do not fit to DPS-B or other helical/spiral-spline drives; those use Type IH.

• Do not mix Type D and Type I propellers, or different Type I sizes.

• Volvo recommends Type F/FH stainless propellers for six-cylinder diesels, engines above 240HP or boats capable of more than 38 knots.

• Final size selection depends on engine output, gear ratio, hull weight and achieved wide-open-throttle RPM.

  

• HP Range: Normally used within the Type I aluminium application range; Volvo recommends stainless Type F/FH above 240HP

• Engine / Drive Type: Volvo Penta DPS/DPS-A counter-rotating sterndrive propulsion

• Year Range: Approximately late 2000s onward as the Type I replacement for Type D sets

  

🔌 Function

  

The counter-rotating front and rear propellers convert drive torque into balanced thrust. Their matched blade geometry improves acceleration, tracking, grip and low-speed manoeuvrability while cancelling most propeller-side force.

  

Common signs of failure or incorrect fitment:

  

• Bent, cracked or heavily eroded blades

• Hub slip or rubber-bushing damage

• Vibration following impact

• Engine cannot reach specified full-throttle RPM

• Mixed front/rear sizes or incorrect spline type installed

  

📦 Condition

  

• Genuine Volvo Penta part

• Brand new

• Supplied in original or equivalent packaging
