COUNT your splines, though. If you have an odd ball lower unit on it or it’s not really a 1970 (SERIAL NUMBER!) it could have a different spline count.
Take the plug wire off and take out the spark plug. Put the shift in forward. Hold the flywheel and attempt to turn the prop counter clockwise by hand. If it spins but the prop nut doesn’t, the hub is spun. You can do this on a little motor.
Long live American manufacturing!
