Customer Questions & Answers

  1. Q Would a gc 190 work? answer now
    Asked by Zach on June 12, 2021 11:32 pm

    a GC190 will work for this pump.

  2. Answered by the admin

    The Honda GX270 usually has a 1" solid shaft, this pump/gearbox combination requires a 3/4" solid shaft.  A GX160 would be a good fit.
