I have 2 older Merc props and I am trying to find out what year and which size motors they will fit.
prop number [1] 4877338 A45 11 [2] 4877348 A40 21P Thanks
These will fit MANY motors 40-140 HP 4 1/4" gearcase thru hub exhaust 15 spline. I suggest you go to the Michiganwheel website and download their prop catalog.
