Volvo Penta propeller B4 Duoprop front propeller, Part number 854825.
This is a B4 series front Duoprop propeller for the DP drives up to DP-E, 290-DP and 280-DP Sterndrives.
Type B propellers (front and rear) are sold individually as spare parts. Type J propellers should be used if you require a set.
When going from B series to J series, add one number - IE B3 converts to J4
If your existing set is badly pitted, or bent or the bushing is worn, then it's time to consider changing your props before they fail. A bent prop causes vibration risking water entering the lower gear case, through the drive shaft prop seals.
Genuine Volvo Penta propellers are covered by our standard 12-month warranty. Have them supplied and installed by us or another authorised dealer, and we’ll extend your warranty to 24 months.
B series is the type for a 280/ 290 DP Sterndrive, and 4 is the size of the Duo-prop. The existing size should be stamped into your existing props. If you need help sizing the correct size for your boat, please contact us first.
Please note: 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 on twin installations).
