I have a 1979 Sea Ray with a Mercruiser I/O. The shifter is really sloppy/worn out. Is rebuilding the old one or purchasing a new one the best option? If a new one is the way to go, I am looking at the Teleflex CH7500 or the SL3 as a replacement. Not having a sample to check out, it is difficult to decide which one would be better. Does anyone have any experience with replacing their control with one of these or rebuilding the old mercontrol? <br /><br />Thanks for any input.
