    I don’t think it’s an SRX. It has three 9’s cast into it. One on each blade near the hub. They are 9’a or 6’s but I think it’s a 999 prop just how it reads to me at least. It’s in damn near perfect condition though

    Looks like an SRX to me. Maybe a 29 worked to a 30? Did anyone copy the SRX prop with how the hub is installed?

    SRX that's been modified substantially. Reduced diameter and heavily cupped, machined at both ends of the hub probably to fit a Merc shaft better.

    Can hardly wait to try it out. It came with what looks to be a custom made thrust washer too

    The SRX hub is too long for a Merc shaft. The machining was to shorten it for a better fit. The thrust washer you have may be thinner too. You'll likely need a cut down nut to install it with a flat washer.

    This is a stock one installed on a Merc. If it doesn't fit right on yours, I'm sure it's Trump's fault according to what I see on Scream and Fly.

    Somebody did a nice job there, you can get a lock ring on there with a full nut. That prop should have a ton of lift with all that cup.
