23427077 Propeller | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta three-blade nibral propeller for Volvo Penta IPS 2, IPS 20, the front half of the type P7 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.

🔌 Function

Meets the water first, ahead of the drive, and turns engine torque into thrust as the leading half of the counter-rotating pair. The P7 designation is what matches the propeller to the hull and lets the engine reach its rated wide-open-throttle speed.

⚠️ Common Signs of Failure

• Vibration that rises with shaft speed
• Top speed down or the engine short of its rated maximum revolutions
• Blade edges nicked, curled or bent back
• Cavitation pitting or corrosion craters on the blades
• Fouling built up on the blade faces

🛠️ Service Notes

• This number is one propeller of a pair - order the Type P7 rear 23427087 with it, or the complete P7 set 23427067, because a mismatched pair will not let the engine reach its rated speed
• The front propeller 23427077 is published at 20.865 kg, heavier on its own than the 20.412 kg published for this complete set, so one of the two figures is wrong - order by the P7 designation and treat neither as a shipping 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
• Fit front and rear to the same type code - complete set 23427067.
• Line cutter 21686494 is the one listed for Volvo Penta IPS 2, IPS 20.
