that water tube did not become short…so it should fit properly….
I can’t see it close up and but since your water pump upper half looks symmetrical in the parts listing could it be installed backwards 180 degrees
btw a 1960 18hp seems like a FD18 ?? not a FD 14 which is nowhere to be found at marineengine.com
btw silly question but if you paid the man to fix it ….. could you not ask him to fix it good to keep a good customer ?
