Another question. I have a leaking o ring (1959 Johnson Super Seahorse 50hp). I have drained the lower unit, oil was milky so I know water got in. I want to replace the ring and make sure nothing got rusty in there. Is there an easy way to remove those darn screws, I cant get any loose and I dont want to strip them.<br /><br />Thanks!!<br /><br />Daron<br />Mahomet, IL
