so i just bought a lower unit off of ebay for my 67 Merc 500. my original lower unit had so much corrosion it was breaking apart and the bearing carrier was stuck in the case.
I'm not familiar with the shifting mechanism on these mercury outboards, First mercury outboard I've owned. so on both lower units the prop spins in forward when i turn the drive shaft engine rotation (Clockwise). when i turn the shift shaft on the original lower unit it spins almost 360 degrees (Probably 315 degrees) and i felt it contact nothing except for the sides of the case i presume. the lower unit i bought off of ebay (Freshwater unit & very clean looks like no one ever opened it up) the shift shaft spins 360 degrees and continuously spins in either direction and i feel it nothing as well. i know there is a cam follower pin in the end of the propshaft that rides on the shift cam that shifts the clutch dog.
Anyone have input on these units and how they shift when not connected to the motor?
