This Solas aluminium Duoprop propeller set for Volvo Penta DP 280/290 is model A3 in the Duoprop type A series. The set is supplied as a pair with a front and a rear propeller and is intended for diesel engines with Volvo Penta DP 280 or DP 290 drives.
The front propeller has 3 blades, a nominal diameter of 15.5", a pitch of 17", and 27 splines. The rear propeller has 4 blades, a nominal diameter of 13.75", a pitch of 17", and 19 splines. Both aluminium propellers have rubber-cushioned hubs and work as a counter-rotating propeller set on the same Duoprop drive.
The model code A3 indicates the size and load characteristics of the propeller set. The correct propeller selection depends on factors such as boat type, engine, gear ratio, maximum speed, and the engine's operating RPM. Type A, B, and J propellers must not be mixed, and both propellers on the drive must have the same type and size code.
OEM and component references
The complete A3 set corresponds to Volvo Penta OEM no. 854766, which replaces the previous set number 852683. The OEM references for the individual A3 propellers are 854776 for the front and 854786 for the rear; the previous numbers are 852239 and 852241 respectively.
The Solas component number for the front propeller is 8512-155-17, while the rear propeller has the component number 8513-138-17. Together, the propellers form the complete A3 set and should not be mixed with propellers of a different type or size code.
Installation
OEM mounting parts must be used, and the installation may require special tools. Depending on the specific drive configuration, M16 or M20 propeller cone kits are used. Relevant mounting references include 872614 and tool kit 854668 for M16, as well as 872549 and tool kit 873058 for M20. Spacer ring 853676 is intended specifically for type A propellers.
