# 21924247 Propeller | Genuine Volvo Penta Part

## 🔧 Product Description

Type J is a completely modern aluminium Duoprop range designed for the classic Volvo Penta 280, 290 and DP Aquamatic sterndrives. The patented blade geometry and large propeller diameter provide optimal efficiency as well as quiet and smooth operation, and a special high-strength aluminium alloy with a squeeze casting process makes the propellers stronger and more durable than traditional die-cast propellers. Four layers of paint ensure excellent corrosion protection performance. This is the J7 rear propeller; the matching front propeller is 21924227, and the pair is also listed as set 21924267. Every set of Duoprop propellers is designed, tested and manufactured together, so the front and rear propellers of a dimension belong to each other.

## 🚤 Compatibility

-   **Engine Family:** AD, D, TMD, DP, HS, TAMD, KAD, KAMD
-   **HP Range:** Approximately 290 HP

## 🔌 Function

The trailing propeller of a counter-rotating Duoprop pair, turning the opposite way in the front propeller's wash and recovering the swirl left in it as extra thrust, which is what gives a Duoprop its grip and straight tracking.

## ⚠️ Common Signs of Failure

-   Vibration through the hull that worsens with speed
-   Lost drive or slip under load with the engine revs climbing
-   Blade edges chipped, bent or curled after a strike
-   Cavitation pitting on the blade backs
-   Splines and thrust faces worn or picked up when the propeller is pulled

## 🛠️ Service Notes

-   Order by the J7 code marked on the propeller and the blade count rather than by weight, which does not step with the dimension in this family
-   Pair it with front propeller 21924227 and keep both propellers at the same J size, replacing them together
-   Volvo Penta's instruction for these drives is to fit stainless Type C propellers instead on six-cylinder diesel engines, on engines over 240 hp, and on boats capable of more than 38 knots (45 mph)
-   Always use type C stainless steel propellers in 6-cylinder diesel engines or engines exceeding 240 hp or capable of speeds above 38 knots (45 mph).
-   Type J sizes are not equally transferred from Type A or Type B sizes - an A5 propeller does not correspond to a J5 propeller. Consult a Volvo Penta dealer for the right size, providing the maximum boat speed and engine rpm if possible.
-   Do not mix Type A, B and J propellers. Always use propellers of the same type and size on the drive, or on both drives in twin installations.
-   Installation hardware, types A, B, C and J: propeller cone kit M16 872614 or M20 872549, propeller nut 3851334, thrust rings 3858458 and 3858457.
