Evinrude used the Tillotson MD on three of their late 1940 & early ’50s outboards. The bolt pattern was the same but the hole through the center was different. The float bowl gasket (0551142) was the same and we sold hundreds of those because they seemed to fit everything. I am sure an early ’50s Evinrude neutral clutch Fleetwin would fit. Be sure you remove the high speed needle valve before you separate the upper & lower carburetor castings. Otherwise you WILL bend the needle and be required to get a new one. Good Luck . . .
