Re: omc cobr***
Ist, I'd ask for a service history on the unit. Did the orginal purchaser have the OMC cable/gears recall done?? Have him show all the repair orders he's got. Second, Stand next to the outdrive on the driver's side. Push the lower unit to port and look up at the shift cable. It should be a red plastic coated cable and the integrity of that cable should be OK. Look closely !! 3rd, Go for a ride. check for 100% operation. Shifts EZily and accelerates correctly. No bumps, jerks , noises out of the ordinary. They really a pretty good system. They just have to work correctly. Changing a shift cable on a Cobra is EZier than on a MerCruiser !! But you do need a manual if you're gunna attempt to dso any sewrce yourself. AND, a local knowledable dealer is helpful.
