Hey Ya'll, Here's my big tool I promised. Its a big shaft. Ok, for the hot rod boat folks, it's an engine alignment tool for Mercruiser stern drives. Cost: one 12 pack of Budwieser to my machinist buddy to turn a scrap piece of shaft stock. This one only has the small step for Alpha drives, the Merc tool has two steps for different engine couplers. Total length 22" x 1.375", first step
2 1/4" long & 1.010" dia.--second step 2 3/4'' long & 1.150" dia.
