I inherited a 7.5 hp Mercury 2-Stroke. Has a Thunderbolt ignition. The S/N is 3622828. I can't find anything on the official Mercury web site. Can anyone tell me hat year this motor is? Also, it runs great but the water pump impeller appear to be bad since it doesn't spit any water out when I crank it. How easy is this to replace and is there an instruction manual availabel for this?
Thanks!
