HI I need help I just got a hd 20 2.5hp 1941 johnson engine I got it to run good but It's not pumping water I took it apart and cleaned all the passages but it still won't pump any water ?<br />I think it may need a new water pump but I don't know if I can find one for such an old engine.<br />I woundering if It's worth fixin.<br />I didn't pay much for It but with shipping it's not something I can just give up on any help would be great thanks.
