This Solas stainless steel Duoprop propeller set for Volvo Penta DP 280/290 is model C3 and is a complete, counter-rotating propeller pair with one front and one rear propeller. The set is intended as an OEM-compatible replacement for Volvo Penta Aquamatic DuoProp DP280 and DP290 drives with 27 splines on the front shaft and 19 splines on the rear shaft.
Both propellers have three blades and must be used together as a matching set. The front propeller is left-rotating, while the rear propeller is right-rotating. The design features pressed rubber bushings in the hubs and is manufactured without thru-hub exhaust.
The propellers are made of stainless steel with thin, strong blades. The design provides good thrust and is developed for acceleration and top speed. The material and blade design also provide high resistance to cavitation, impact, damage, and corrosion.
The shock-absorbing rubber bushings reduce vibrations and strain on the drivetrain. Galvanic isolation in the hubs also helps protect the drive from corrosion caused by the propellers.
When installing, check clearance, shaft version, and correct mounting hardware. The M16 propeller cone kit 872614 or M20 propeller cone kit 872549 is used depending on the drive's shaft version. Tightening torques and mounting sequence must follow the drive's OEM manual. Mounting hardware is not documented as part of the propeller set.
OEM cross-references
Complete C3 set: 3860878. Newer OEM cross-reference: 3588223. Previous numbers for the individual propellers are 3860604 for the front and 3860605 for the rear; these have been replaced by 3587865 and 3587871, respectively.
The front and rear propellers must be used as a complete stainless propeller pair. Do not mix a Solas propeller with a propeller from another manufacturer on the same drive.
Always check drive model, shaft profile, propeller type, and original part number before purchasing.
