23442955 Propeller Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta type T5 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 T5 designation records.

⚠️ Common Signs of Failure

• Vibration through the deck that rises with revolutions
• Boat slow to plane or short of its usual speed
• Blade damage after a rope strike or grounding
• Cavitation pitting across the blade faces
• Fretted hub taper or damaged blade roots found on strip-down

🛠️ Service Notes

• Both propellers of a drive must carry the same designation - fitting a T5 propeller against any other size loads the engine wrongly, so renew the pair together and check the marking on each before fitting
• The published weight is identical to that of 23442956 (T6), so weight cannot separate the two - 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 T/TS series runs TS3, TS4, TS5, TS6, T2, T3, T4, T5, T6, T7, T8 from moderate top speed to high top speed; T5 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.
