The part numbers I2F 21260642 and I2R 21324312 are a matched Volvo Penta DPS Duoprop I-series (I2) propeller set, consisting of a front (LH) and rear (RH) prop. This I2 set is the newer-generation replacement for the older D2 Duoprop set, offering comparable pitch with improved efficiency and grip. These props are designed for DPS/DPS-A drives and must always be installed as a matched pair—D-series and I-series props are not interchangeable or mixable.
