Re: Johnson 70HP 1979 Lower End.
Hi Sirius3K,<br /> You'd probably be better off taking that one to a shop - later style OMC units are a pain to work on unless you have the right tools and jigs to set up the gear lash tolerances. Decent used lower units turn up on eBay all the time for $100-$300, but it can be a crap shoot.<br />- Scott
