Impros Yamaha Hooker Impeller (144mm)

The Impros Hooker 144mm impeller for the Yamaha is a 3-blade large hub diameter, radial edge design stainless steel impeller designed and intended for Bottom end and “Hook up” for Freestyle and Freeriders on a Super Jet, Blaster, or similar ski that utilizes the 144mm pump and want maximum AIR for tricks.

Designed around maximizing pump efficiency and bottom end, this is a new radial edge design, large hub (75mm), and is set back 5mm (2mm further than we can go with a small hub impeller). It is a rec finish Yamaha impeller that we will have available for the 144mm stock pump, and 144/142/140mm Magnum pump. Designed with a steep root angle to load the pump well.

Material is a 17-4 stainless steel cast. Dynamically balanced, comes with our Recreation polish, and with an impeller tool and rubber nose seal.

We have it available in a variety of pitches for different engine set ups. The pitches available are 9/15, 10/16 and 11/17. These numbers are much different from other impeller pitches you have heard of. While they are very low, and directed at bottom end “Hit”, the root angle, blade length and other geometric differences set the Hooker apart from the others. We also produce “more aggressive” custom pitch Hookers for engines that require it, for an additional charge.

The 10/16 and 11/17 Hooker has also been one of the most competitive impellers used for closed course racing limited and spec class Super Jets and Blasters.

As stated above, they fit in the stock 144mm Yamaha pump, Solas 12 vane pump, Skat Trak Magnum pumps (with a shim), and TBM Super Pump Cones.

Hex tool, rubber nose seal and Impros Hooker sticker included in purchase price. We recommend also buying a Driveshaft holding tool (WR004H) as well, for ease of installation.
