Thrust Innovations 155mm Shredder Setback Mag Pump!
The most affordable high performance mag pump on the market! 75mm large "mag" hub with 14 vanes and 2" setback. Includes a delrin pump cone, 4 pre-tapped cooling fitting holes, and locator pin spots.
Stainless steel stator section with an aluminum wear ring - which means no swelling and some weight savings. The wear ring is also longer than a standard Yamaha jet pump to keep weight lower. This pump weighs in just under 10lbs.
The 2-piece design requires the use of a pump shoe seal and long pump bolts (like normal OEM Yamaha pumps).
*155mm pumps are a good combination for bottom end hit with a 701 & 760cc setup. And it is a perfect match for 900cc+ stroker and stock stroke engines.
*PLEASE NOTE - This pump assembly does not include pump bearings (setback specific) and seals, long pump bolts, a pump shoe seal or a driveshaft.
