'97 J60 TLE. BRP shows two different shafts. One is a 20", the other a 25". One is part # 437376, the other is 437379. Mine measures 19" to the top of the impeller boot. So it can't be a 20" can it?? Don't they count total shaft length in the measurement? One nutty thing about this shaft, the part # is stamped right on it, but BRP doesn't show it. I won't come up. The part # 2 digits before it shows and the # one digit after it shows, but not part # 437378. Any help on this is appreciated. Thanks, KR
