    Impeller ?

    I have a 50 thou setback impeller, Is there anyway to make it not setback? Thicker washer maybe, and if so were do I get one? What would be the pros and cons setback or not? I'm trying to pick up a little more RPM.

    Wow, unbelieveable 1200 grate speeds for those mods in 90 degree heat.. Good job. I am making a post on fine tuning you rpms without touching your impeller. Chek it out in 20 minutes. Ross

    Your signature is very close to what I am planning for the wifes boat.
    What RPMS are you turning now?

    7060 rpms with a Fercho spec 14/23, in the heat it would be better with his 14/22.
