24044446 Propeller Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta four-blade nibral propeller for Volvo Penta IPS 1, IPS 10, the rear half of the type TS6 counter-rotating pair. It is machined from the specially developed nibral (nickel-bronze-aluminium) alloy Volvo Penta uses for its IPS propellers, which gives minimum growth, excellent durability and corrosion resistance. 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. The rear propeller carries the patented flow deflector, which controls the water flow and minimizes pressure and wear on the propeller shaft seals.

📋 Kit Contents

🔌 Function

Runs behind the front propeller and turns the opposite way, recovering the swirl left in its wake as further thrust and cancelling the sideways pull a single propeller would produce. It is also the propeller the line cutter mounts to, and its TS6 designation has to match the front propeller for the engine to be loaded correctly.

⚠️ Common Signs of Failure

• A grumble or buzz from the drive that comes and goes with load
• Slow acceleration and a boat reluctant to lift onto the plane
• Blade edges nicked, bent back or eaten away by cavitation erosion
• Rope, netting or fishing line wrapped between the propeller and the drive housing, sometimes with oil weeping from the seal behind it
• On a twin installation, one drive pulling different engine speed or load from the other at the same throttle

🛠️ Service Notes

• This number is one propeller of a pair - order the Type TS6 front 24044396 with it, or the complete TS6 set 23442966, because a mismatched pair will not let the engine reach its rated speed
• 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
• Check the shaft seal and clear any line from behind the hub while the propeller is off, and confirm wide-open-throttle speed against the engine rating after any propeller change
• Fit front and rear to the same type code - complete set 23442966.
• Line cutter 23062729 is the one listed for Volvo Penta IPS 1, IPS 10.
