There is a really good looking 1989 17.5 ft boat with a 2.3L Ford engine and a OMC Cobra drive at a auction tomorrow. The auctioneer tells me that the boat won't shift into reverse and needs a shift cable. I like the looks of the boat , but am I asking for trouble buying buying this Cobra? I have owned and worked on Mercruisers in the past, but never an OMC. It will probably sell quite cheap, but then I have seen where free was too expensive.
