Direct-fit Solas Amita 3 aluminium propeller for selected Mercury, Mariner and Force outboards using a 3-inch gearcase, 10-tooth propeller shaft and through-hub exhaust. This three -blade right-hand propeller has a nominal 10.3-inch diameter and 12-inch pitch. Fitment and selection check: Match the exact engine model, model year, 3-inch gearcase, 10-tooth spline, through-hub exhaust and right-hand rotation. Compare the current propeller size and confirm that the engine reaches its specified wide-open-throttle RPM range after installation. This propeller is not for MerCruiser sterndrives.

No. Solas 1211-103-12 is a direct-fit Amita 3 propeller with a pressed-in rubber hub. Does it fit every Mercury or Mariner 9.9–25hp outboard? No. Fitment is limited to the listed model ranges using a 3-inch gearcase, 10-tooth spline and through-hub exhaust. Later four-stroke engines can use different propeller families. Does it fit MerCruiser sterndrives? No. This propeller is for the specified Mercury, Mariner and Force outboard applications, not MerCruiser sterndrives. How do I know whether 12-inch pitch is correct? Compare the size of the currently fitted propeller and check the engine manufacturer's specified wide-open-throttle RPM range. Propeller pitch depends on the boat, engine, load and normal operating conditions. Is the propeller mounting hardware included? No. Check and reuse the correct engine-specific hardware where serviceable or order the correct replacement hardware separately. Before ordering: Match the engine model, year, gearcase, spline count, exhaust arrangement, current propeller and wide-open-throttle RPM requirements before installation. Show more
