23427144 Propeller Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta type PS4 nibral propeller set for Volvo Penta IPS 2, IPS 20, specifically developed for IPS with D11 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 PS4 designation records.

⚠️ Common Signs of Failure

• Vibration through the hull that rises with shaft speed
• Loss of top speed or the engine unable to reach its rated maximum revolutions
• Blade edges nicked, bent or torn from a strike
• Cavitation pitting or corrosion craters on the blade faces
• Marine growth built up on the blades

🛠️ Service Notes

• Both propellers of a drive must carry the same designation - fitting a PS4 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
• Genuine Volvo Penta propellers carry a 12 month warranty, extended to 24 months including labour when supplied and fitted by an authorised Volvo Penta dealer
• The type P/PS series runs PS4, PS5, P1, P2, P3, P4, P5, P6, P7, P8 from moderate top speed to high top speed; PS4 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 21686494 is the one listed for Volvo Penta IPS 2, IPS 20.
• Volvo Penta water-resistant multi-purpose premium grease is recommended for propeller shafts and all other propeller components.
