    What size wrench for FZR impeller???

    Title pretty much says it. I have the shaft holding tool on the way. For the impeller itself though, 26mm is too small, 27mm is too big, and 1 1/16 is also too big (exact same size as 27mm). Did they really make it some odd size so regular tools can't be used? What's the secret?

    The stock prop will require a 27mm box wrench which is sold at sears. They only sell the 12-point version but it works fine. The skat/ solas tool requires a 1inch 6 point box wrench.

    The 26mm didn't fit so I took it back. Maybe it's just a much tighter fit than I thought it would be. I guess I'll go back and get it again.

    It's 27mm. I could only find that size box end in 12pt so I use a 1-1/16 6pt. Don't use 12 pt because it's likely to slip & damage the impeller, especially if it's the first time it is being removed. Also, never use an open end wrench because it'll collapse the impeller.

    Make sure to use anti-seize when reassembling & make sure to torque it on good, otherwise it'll be a bitch to get it off next time.

    Tried the 26mm again. It is 26mm, but a very tight 26mm. Guess I just didn't try hard enough the first time. Thanks guys. BTW, the service manual calls for locktight, not anti-sieze, for the impeller.

    If it was me, I'd use anti-seize. The torque on these things is crazy; adding loctite to the mix will probably make removing that impeller again a bigger b!#$%%.....
