Why doesnt 25 hp mercury 2 stroke reverse lock hold motor from coming up in reverse?

The reverse lock on a 25 hp Mercury 2-stroke motor may not hold due to several factors, such as misalignment or wear on the lock mechanism, a faulty or damaged locking pin, or improper adjustment of the reverse lock assembly. Additionally, if the motor is subjected to excessive force when in reverse, it can overcome the locking mechanism. It's important to inspect the components for damage and ensure proper maintenance to resolve the issue.
