A direct factory replacement for Mercury HP 525 EFI, HP 600 SCi and HP 700 SCi engines. Downturn collector provides improved water fill. Works with existing tailpipes. More equalized primaries for greater performance in horsepower and torque. Using the same high quality 316L stainless steel that is used in our race systems. Patented “Cool Collar” design provides a short hot section at the flange, which helps minimize the possibility of water ingestion in to the engine.
