Hi! I recently purchased a 1979 18' Cobalt. I believe it has a Ford 302 block, and the outdrive is a Mercruiser with an "888" label on it. My insurance agent wants an engine serial number, but I cannot find it anywhere. He probably wants the outdrive serial also, and I haven't been able to find that either. Any suggestions on where to look for these numbers would be greatly appreciated! Thanks in advance for any help you can give me.
