I went today Monday march 16, to look at the motor, it is a model 4375, they have all the paper work and manual. they also have the original metal box that has the rebuild kit, flywheel with stator plate, new prop, new carb, piston with rings push rod, bearings and gasket set, spark plugs. the above picture is correct, I see the picture talks about a reverse, I was unsure what that was, it seems to be on a cam plate, also the lower unit gear housing is very large. the motor was owned but a Brian Carlson out of Princeton IL. was sold to this marina in 1985
