    I just finished putting my 1945 Neptune 15B2 (2hp) back together starts right up. When bought it did not have a prop or nut bought a set prop fits great but nut does not thread on. Threads look fine. Anyone have an idea what thread it should be?

    The 1936 4 hp here in my shop is 1/2-13. Does that help?

    thanks Richard that is what I thought it looked like may get a die and see if I can get the threads cleaned up. Did not have a nut or prop with it when it was given to me bought those and coil from Doug Penn cleaned out the tank and carb cleaned and adjusted points fires right up every time. may have to get a canoe to run it on

    checked things out tonight 1/2×13 standard coarse thread. Put new shear pin on with prop nut and new cotter pin ready for the test tank tomorrow. Starts easily so will see how it pumps water and let it run for a while.
