# 21821365 Propeller Kit | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta type QS5 nibral propeller set for Volvo Penta IPS 3, IPS 30, specifically developed for IPS with D13 engines to give outstanding efficiency, onboard comfort and manoeuvrability. The set supplies the matched three-blade front propeller and four-blade rear propeller together. Volvo Penta IPS turns the propellers round to a forward-facing position, so the twin counter-rotating propellers pull the boat through the water rather than push it, and optimal interaction between the front and rear propeller holds performance and fuel efficiency across the whole speed range.

## 🔌 Function

Supplies both halves of the pod's counter-rotating pair, sized as one unit so the two propellers share the load the way the drive was designed for and let the engine reach its rated wide-open-throttle speed. Changing size changes how hard the engine has to work, which is what the QS5 designation records.

## ⚠️ Common Signs of Failure

-   Engine RPM falls outside the specified range
-   Propeller-shaft seals or bearings show abnormal load

## 🛠️ Service Notes

-   Both propellers of a drive must carry the same designation - fitting a QS5 propeller against any other size loads the engine wrongly, so renew the pair together and check the marking on each before fitting
-   In every size in this run where a set and both its propellers carry a published weight, the two propeller weights do not add up to the set weight, so weight identifies nothing here - order by the designation
-   For commercial running in polluted or debris-laden water Volvo Penta also lists the QE series, which has thicker blades than the Q for extra strength at a slight cost in top speed, and is approved for D13 IPS900, IPS1050 and IPS1200
-   The type Q/QS series runs QS4, QS5, Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8 from moderate top speed to high top speed; QS5 sits of 10 on that scale.
-   Both propellers on a drive must carry the same type code - the front and rear are matched for torque distribution and mixing codes changes how the load is shared.
-   Line cutter 21686496 is the one listed for Volvo Penta IPS 3, IPS 30.
-   Volvo Penta water-resistant multi-purpose premium grease is recommended for propeller shafts and all other propeller components.
