23442964 Propeller Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta type TS4 nibral propeller set for Volvo Penta IPS 1, IPS 10, specifically developed for IPS with D4 and D6 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 TS4 designation records.

⚠️ Common Signs of Failure

• Vibration that changes with revolutions
• Poor acceleration and a boat down on cruise speed
• Chipped or curled blade tips after debris contact
• Cavitation pitting on the blade backs
• Fretted hub taper or corroded blade roots on strip-down

🛠️ Service Notes

• Both propellers of a drive must carry the same designation - fitting a TS4 propeller against any other size loads the engine wrongly, so renew the pair together and check the marking on each before fitting
• The TS4 front 24044394 and rear 24044444 are published at 13.146 kg and 10.095 kg, 1.524 kg more than the 21.717 kg published for the set, so the figures do not reconcile - order by the TS4 designation, never by weight
• 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 T/TS series runs TS3, TS4, TS5, TS6, T2, T3, T4, T5, T6, T7, T8 from moderate top speed to high top speed; TS4 sits of 11 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 23062729 is the one listed for Volvo Penta IPS 1, IPS 10.
• Volvo Penta water-resistant multi-purpose premium grease is recommended for propeller shafts and all other propeller components.
