I have a 1993 four winns 230 horizons with 454 engine, and a king cobra outdrive. I replaced a broken lower shift cable about 3 weeks ago. Ever since then, I've had nothing but problems. If I put the earmuffs on it and run it, I can get forward, neutral and rverse. But as soon as I put it in the lake it will go into forward maybe once, I can always get it to go into reverse and neutral, but when I put it in forward it just revs up the rpm's. so I take it home and hook it back up to earmuffs again I can get forward again. this is getting very frustrating, if anyone has been through this before, please let me know how to fix it. thanks, john
