    Mercury OEM uses a lock nut. But even that, at those RPMs, if not properly seated in the tab washer it could back off. Always a good idea to do a quick visual inspection when u strapping and unlocking your motor to be certain it hasn’t been tampered with or somehow backed out. Takes about 2 seconds to look and notice an issue

    Very unlikely. Unless they really just wanted to steal the 16mm nut and not the prop. Does not make sense.

Need to reset my drift, fire it up give it some gas run to new spot and slow down, put it back in gear and nothing. Engine revs but not going anywhere. First thought is I broke a cable that engages the drive mechanism. Well I am close enough to home I can power back on the trolling motor. Get it on the trailer, go to put the engine up and wtf no prop. How does this even happen. Well the long of the short is do not trust the guy before you. The prop must have been installed incorrectly and I paid the price. The PSA check your prop make sure it has a locking washer and is installed correctly. Especially if you were not the one to install the prop that is on your boat.

    Maybe someone was going to take your prop and go home with it????

    Would that affect the torque values for the prop attachment? Those newer systems have different things attached......Jetspray

    Your know, at least I understood how the shear pin worked and they were cheap. I don't understand this new rubber hub thing in the prop. At least I knew how to replace a shear pin.
    More parts = more cost, it is what boating is all about. I used to carry a wrench and extra shear pins in my tackle box just for that, and an extra pull rope in case one broke...….Jetspray

    I'm definitely going to check the cotter pin on my prop after reading this.

    That sucks. Been boating for 50 years and never had a prop come off. I’ve destroyed a few hitting various things though. I actually like the the tabs you bend on Merc’s. They are foolproof.
