This SOLAS adapter kit for New Saturn 3-blade propellers is model UME-KT in the Multi-Fit series. The kit is used for engine-specific adaptation and mounting of compatible propellers on Mercury and Mariner outboards as well as MerCruiser sterndrives.
UME-KT belongs to Multi-Fit group ME and is designed for 15-spline propeller shafts. Documented engine compatibility includes Mercury and Mariner outboards from 135 to 300 hp, including both 2-stroke and 4-stroke engines. For sterndrives, the kit can be used with MerCruiser Alpha One and Bravo One.
The kit's documented components are the UME-TW thrust washer, UME-SP spacer, and MEWS washer. The parts form the necessary adapter solution between the compatible propeller and the relevant propeller shaft.
The primary propeller compatibility is SOLAS New Saturn 3-blade propellers. UME-KT is also registered as Multi-Fit ME Kit with GFN reference 722503 and is linked to compatible SOLAS propellers in the YE/E group. Always check the specific propeller model and the engine's shaft configuration before installation.
