Will a 02 merc 40 hp 2 cyl 2 stroke motor run if you unhook a bad rev limiter?

Unhooking a bad rev limiter on a 2002 Mercury 40 hp 2-cylinder 2-stroke motor may allow the engine to run, but it is not advisable. The rev limiter is designed to prevent the engine from over-revving, which can cause significant damage. Running the motor without this safety feature could lead to mechanical failure or other issues, so it's best to replace or repair the rev limiter instead.
