854828 Propeller | Genuine Volvo Penta Part

🔧 Product Description

Type B is an earlier aluminium Duoprop range for the classic Volvo Penta 280, 290 and DP Aquamatic sterndrives. Volvo Penta has replaced the Type B propeller sets with Type J sets, but the Type B front and rear propellers are still sold individually as spare parts. This is the B7 front propeller; the matching rear propeller is 854836 - 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.

🚤 Compatibility

• Engine Family: AD, D, TMD, DP, HS, TAMD, KAD, KAMD

🔌 Function

The leading propeller of a counter-rotating Duoprop pair, taking the first bite of clean water and turning engine torque into thrust, with the rear propeller behind it sharing the load the drive is designed to carry.

⚠️ Common Signs of Failure

• Vibration that comes on with revs
• Chipped, bent or curled blade tips
• Engine over-revving for the boat speed
• Weed or fishing line trapped at the hub
• Erosion or pitting on the blades

🛠️ Service Notes

• Order by the B7 code marked on the propeller rather than by weight: only 23 grams separate it from the B2 front 854823
• Check the matching rear 854836 for the same damage and keep both propellers at the same dimension
• Do not mix Type A, Type B and Type J propellers on a drive, and use propellers of the same type and size on the drive - or on both drives in a twin installation; Type J is the modern aluminium replacement covering both Type A and Type B sizes, but the sizes do not transfer directly - an A5 is not a J5 - so size an upgrade with your dealer, giving maximum boat speed and engine rpm
• Type J is designed to cover both the Type A and the Type B propellers, but the sizes are not equally transferred. 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.
