23795439 Propeller Kit | Genuine Volvo Penta Part

🔧 Product Description

Type G is the Nibral (nickel-bronze-aluminium) Duoprop range for the Aquamatic DPH drive. The patented blade geometry gives optimal interaction between the front and rear propellers for outstanding efficiency and smooth, comfortable operation, and the extremely strong nibral alloy gives excellent durability with minimal marine growth. A shock-absorbing rubber bushing and galvanic isolation make it a matched fit for the DPH drive. This is the G9 front propeller; the matching rear propeller is 23795449 - no complete set number is listed in this dimension. Every set of Duoprop propellers is designed, tested and manufactured together, so the front and rear propellers of a dimension belong to each other.

🔌 Function

Takes the first bite of undisturbed water as the leading half of the counter-rotating G9 pair, turning engine torque into thrust.

⚠️ Common Signs of Failure

• Vibration through the hull that grows with boat speed
• Blade tips chipped, bent or curled after contact with the ground or debris
• Engine revving higher than normal for the thrust it gives, which points to the rubber bushing having slipped
• Loss of top speed, or the engine no longer reaching its rated speed
• Rope, weed or fishing line wound in tightly behind the hub

🛠️ Service Notes

• Front and rear must carry the same size code, and type G and type H propellers must never be mixed - use the same type and size on the drive, and on both drives in a twin installation
• Moving to the stainless steel type H propellers keeps the same size, so a G9 corresponds to an H9, but the propeller cone has to be changed as well, using cone kit 23000185
• Clean and grease the propeller shaft splines on refit and check the bushing for any sign of having slipped
• Type G propeller sets have been replaced by either Type H propeller sets or by individually sold Type G front and rear propellers - no complete Type G set number is listed.
• Upgrading from Type G to Type H keeps the same sizing: a G6 propeller corresponds to an H6 propeller. The propeller cone must be replaced to fit Type H propellers (kit 23000185).
• Do not mix Type G and Type H propellers. Always use propellers of the same type and size on the drive, or on both drives in twin installations.
• Installation hardware, type G: propeller cone kit 21829326, lock bolt M12 991609, rear propeller nut 3863213 and front propeller nut 23952642.
