The Impros Hooker 155mm 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 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 3mm. It is a rec finish Yamaha impeller that is compatible with the 155mm pumps. 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, impeller tool and rubber nose seal.
It is available in a variety of pitches for different engine set ups. The pitches available are 9/15, 10/16, 11/17, 12/18 and 13/19. 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.
Hex tool, rubber nose seal and Impros Hooker sticker included in purchase price. We recommend also buying a Driveshaft holding tool (PN# 06-04-022) as well, for ease of installation.
