80 HP Opt J Outboard

Mercury Jet Outboards are designed with the power and the weight to cover any shallow-water jet boat application. Choose from Electronic Fuel injected FourStroke models with horsepower ranging from 80 to 110 horsepower. The new Jet OptiMax 80 and 110 models are poised to become the power of choice for jet boat operators everywhere. Compared to four-stroke competitors in its class, the lightweight two-stroke Direct Injected OptiMax Jet outboards feature lightweight, high-power performance, with outstanding holeshot and acceleration, perfect for shallow-water jet applications. The Jet 80 and 110 OptiMax outboards feature OptiMax fuel system technology, a testament to their quality, reliability and durability.

Water is drawn into the unit through the intake grill by an impeller, driven directly by the engine driveshaft. The water is then forced at high pressure through an outlet nozzle, creating thrust that drives the boat forward. To obtain reverse, a gate lifts into position over the outlet re-directing the pressure stream in the opposite direction.
