Boat water-jet drive MODEL 751

These jets are suited to naturally aspirated 4 cylinder engines such as the Subaru, Nissan’s and GM Ecotech engines. The 7.5 inch single stage is ideally suited to engines that have moderate torque and horsepower characteristics. The smaller jet allows the engine to accelerate through the bottom RPM range quickly (which is where these smaller engines often struggle) and into the mid-range and top-end where they produce their most usable power. Suitable for engines from 90 to 200 hp. This jet was originally developed for use in our small Puddle Hopper boats to fully utilise the potential of the smaller 4 cylinder engines and it can easily be upgraded to a two stage should the engine be supercharged or turbocharged in the future.
