    Little Mercs have very small, high pressure/low volume impellers, sort of like a 9.9/15 OMC but smaller and tighter. They take a bad set and have a strong tendency to bend a bade backward. In my experience, anything more than two years old starts to be suspect. So, 35 years…..? What if you did have a failure and toasted that beautiful thing? I know I wouldn’t trust a 35 year old Merc impeller; but your luck may vary….

    Long live American manufacturing!
