Thunderbolt IV ?????? or V ???

The rev limiter is a separate component on TB IV's and not built into the module. It may or may not be included with what you're looking at. It would be at 5300-5350rpms.

Its a TB IV and The limiter looks like a factory Merc one. Should be 5300-5350rpms. You don't have to hook it up at all if you don't want. If it came off a 500HP, then it has a 20* advance module.

Thats a good price if everything is in good shape and its what you need. New, its about $500 worth of stuff.
