Polastorm Soltiga 3 duplex stainless steel propeller is a right-hand, 3-blade boat propeller with a diameter of 15 1/4″ and a pitch of 19″. The propeller is designed for a 4 3/4″ gearcase and uses a separate, engine-specific hub kit.
The propeller is manufactured from duplex stainless steel according to ASTM A890 Grade 4A and has a polished finish. The high chromium content contributes to the material's corrosion resistance, while APC casting technology – Aerospace Precision Casting – provides high material density and physical strength.
The size specification 15 1/4 x 19 indicates a diameter of 15 1/4″ and a pitch of 19″. This variant is right-hand rotating. The Soltiga 3 geometry corresponds to the Solas Lexor and Solas Rubex L3 propeller profiles, but the designation is a profile reference and not an OEM number.
This variant is recommended for Suzuki engines of 175–225 hp and for other engine brands from 250 hp and up. Final compatibility depends on the engine variant, model year, 4 3/4″ gearcase, propeller shaft, and number of splines.
The propeller is supplied without a hub and shock-absorbing insert. The correct hub kit must be ordered separately and is selected based on the engine. Documented hub options include F21 for Mercury, F23 for Yamaha, F29 for Tohatsu/Nissan, and F42 for Volvo SX, as well as additional engine-specific variants. Depending on the variant, hub kits consist of a shock or shear-protecting insert, thrust washer, front washer, spacer, and nut.
