This Solas aluminum Duoprop propeller set for Volvo Penta DP 280/290 is model B6 and consists of a front and a rear propeller for the counter-rotating Duoprop system. The set is intended for Volvo Penta DP 280 and DP 290 drives and has the OEM set reference 854819.
The front propeller has three blades, while the rear propeller has four blades. Both propellers feature thin-profile blades and an integrated, pressed-in rubber hub. The counter-rotating design requires that the front and rear propellers be used as a correctly matched combination.
The front propeller is SOLAS 8512-153-21 with a diameter of 15.3 inches, a 21-inch pitch, and 27 splines. The rear propeller is SOLAS 8513-138-21 with a diameter of 13.75 inches, a 21-inch pitch, and 19 splines. Both propellers are made of aluminum.
The Type B system is used with both gasoline and diesel engines. System guidelines include diesel engines up to 230 hp, while the stainless steel Type C is recommended for speeds over 35 knots. The correct B6 size must be selected based on, among other things, engine, gear ratio, maximum rpm, and boat speed.
Propeller types A, B, and J must not be mixed. Both propellers on the same drive must be of the same type and size, and for dual installations, both drives must use identical propeller combinations. Follow the drive's installation instructions and specified tightening torques. Original mounting hardware must be used, and special tools may be required.
