    I have a Shurflow 3901-2214 3.5 gpm fresh water pump that just quit on me.

    I took it apart and the drive assembly mount is cracked. I can’t find the replacement anywhere. Part #94-706-06

    I have found the 94-238-03 lower housing repair kit that looks exactly like what I need, but it is for the 2088 and 2095 series pumps, not my 3901 series.

    Both pumps are 3.5 gpm with 3 chambers.

    Does anyone know if this lower housing for the 2088/2095 pump will fit into my 3901 series pump?

    I struggled with the same issue when my original pump went out. I was never able to find a matrix which would tell me what rebuild kit would specifically work with which pump series. I took it as an "opportunity" to upgrade to a 5 GPM. The 5GPM pump has a slightly different mount-hole pattern. Other than that it was a direct replacement.

    I also went with the 5GPM one when mine crapped out. The difference is nice, especially on your washdown hose.

    Thanks for the replies, looks like I’ll be ordering a new pump.

    Pay attention to wiring spec.

    The 3.5 gpm pump served me well, I’m going to use the same size as a replacement. I’ll verify that the amperage is the same as the original.
