I'm exaggerating a little bit, but the Lower Unit Gear Housing Seal Kit for Johnson/Evinrude 396349, GLM 87601 - Sierra contained every gasket known to man. It was way more than I needed because I wasn't able to get the entire lower unit apart. The internal snap rings stymied me. Nevertheless, the parts that I did use has appeared to solve the leaking oil problem of my 1978 70 HP Evinrude. The price was reasonable.
