Cdi Electronics Mercury Over Reverse Limiter - Cdi Electronics (144-1889-51)

In modern vehicles with internal combustion engines, a rev limiter is a mechanism installed. Its purpose is to keep an engine safe by limiting the maximum rotational speed, which is measured in RPM (RPM). The engine manufacturer pre-sets the rev limiters. There are also aftermarket devices that have a separate controller with a unique RPM setting added. A limiter stops a vehicle's engine from being pushed past the red line set by the manufacturer (literally the red line marked on the tachometer). Engine damage may occur at a point beyond the redline.
