solas yq impeller (big hub) review

[RiverRat]

Any good reviews of this impeller? if so what is your set up?

They are too steep for small engines. Close to a 11-17 hooker.

Talked to thrust innovations and the impeller pitch of these is not like the Hooker impellers with various root angles. Should be able to read pitches normally with special concern like the Hooker

 

[kevbo]

The advertised numbers are meaningless. Out of the box, a YQ-12-18 ran 300rpm lower than a 9-15 hooker. I raised the trailing edge 6mm to make it match the 9-15 load. The YQ would be good for a SS850 or 800cc stroker.
