The Sierra 18-36001 is a seawater pump assembly for MerCruiser engines, covering Bravo drives and V-belt driven inboard V-6 and V-8 engines. It replaces the OEM MerCruiser pump numbered 46-807151A12. The pulley is not included, so it has to come from elsewhere. Check that the engine is a V-6 or V-8 running a V-belt before going further.
Our take
Pulley not included is the line to notice on this pump assembly: it replaces MerCruiser 46-807151A12 for V-6 and V-8 engines, but the pulley has to come separately, so make sure you have a usable one.
