The Mercury 25 hp Jet is designed to get you through some of the most challenging waters anywhere. Specifically engineered to propel boats in shallow water where traditional outboards are unable to operate, Mercury outboard jets replace the gear case with a jet pump that sits even with the bottom of the boat and provides you with the ability to go wherever the fish or fowl are. Mercury Jet outboards are also the power of choice for rescue boats, providing a secure environment around the engine. No matter the adventure, a Mercury Jet outboard will get you there.  The Mercury 25 hp Jet stainless impeller improves performance and withstands harsh, abrasive debris that can be drawn through the pump, such as sand and shells. That ability adds to long-term durability and reliability.
