Adapter kit for Solas New Saturn 3-blade propeller in the UMC-KT variant is a Multi-Fit MC mounting kit for the relevant Mercury C application class. The kit is used when installing New Saturn 3-blade propellers with a pressed-in or fixed hub.
UMC-KT is designed for Mercury, Mariner, and Force applications with a 3-1/4" gearcase and a 13-spline propeller shaft. The engine class includes documented applications from 25 to 70 hp with through-hub exhaust.
Compatible engine models
Mercury applications include 25 hp Bigfoot 4-stroke from 1999–2005, 30 hp Bigfoot 4-stroke from 2001, 30 hp 2- and 4-stroke from 1994–2005, 30 hp Sea Pro/Marathon from 1994, 35 hp from 1984–1989, as well as the 402 and 500 models from 1974.
Additionally, the category includes Mercury 40 hp 2- and 4-stroke, non-Bigfoot, from 1977, 40 hp Sea Pro/Marathon from 1977, 45 hp from 1986–1989, 50 hp 2- and 4-stroke, non-Bigfoot, from 1977, 55 hp/Sea Pro/Marathon from 1995, 60 hp 4-stroke, non-Bigfoot and non-Sea Pro/Marathon, from 1978, 60 hp 2-stroke from 1978, and 70 hp including Model 700 from 1983.
