The module does not have a rev limiter built in. The rev limiter on Merc Racing engines with TB IV's is a separate part.

The rev limiter is part # 41. http://www.mercruiserparts.com/Show_...CAL+COMPONENTS

I wouldn't buy them. Just get a Crane Box with built in rev limiter.Lower cost and more options.
