I'm going to ask what may seem to be a silly question to some, but........

Is there a measurement to tell the difference between a large taper and a small taper on the crankshaft of a 44ci mercury?

I'm in need of another flywheel for my mod motor and I'm unsure of exactly which crankshaft that I have. My current flywheel is of the old style, with the one piece, single cast hub. I would like to get a new style with the two part hub/ring gear. I know that the old style came in both small and large taper and the new style is large taper only, thus my question.
Thanks everyone for your input,

If anyone has a flywheel hub for sale please let me know.
