Hi all! I was wanting to know whats the best way to inspect the transom seal on my 1977 351w with a electric shift stringer outdrive.I dont want to get it out in the lake this spring and it sink! LOL I have a 1977 Cobalt and its been sitting for years.Would it be best just to replace it anyway? Oh one more question, I bought a Repair manual CD for OMC 1964-98 off e-bay and should be here in a few days,has anyone ever bought one of these CD"s and are they clear on the pics? thanks for any help
