What size motor was the lock on? Was it being used as a kicker?
My old Yammy T9.9 kicker had a steering lock to while the new one doesn’t. Since kickers with remote steering are set up with zero friction, the lock held the motor in place while towing. Instead of using the lock, I would leave the tie bar to the outdrive hooked up while towing to prevent the kicker from flopping around from side to side. Yours might have another purpose though.
