The D-75/20 is a Magnum Hooker impeller that is 148mm in diameter, with a 75mm hub (made for a D-75 Magnum pump), and 20mm threads, for a Super Jet, Wave Blaster, or any other model that has a shaft with 20mm thread and is 148mm in diameter. It’s a stainless steel, 3 Blade, radial edge Swirl design.
More and more riders that are dropping big horsepower engines into Super Jets are putting 148mm Magnum pumps in their skis to get Maximum “hook up”, as they start spinning the impeller in their smaller, 144mm pumps.
The impeller is available in many different pitch options, and we can also provide it in 146mm diameter. If you’re looking for a 144mm Large hub impeller, then you want to navigate to the 144mm Hooker impeller available.
We will custom pitch your impeller to meet your needs, are you riding at elevation or with a tune, any modifications? Let us know and we’ll pitch it so you’re getting top performance!
