I have a 1988 renken with a Mercruised 3.0L and Alpha I outdrive. I've been having trouble getting it to shift into reverse. I had the lower unit apart to replact the pump and was able to shift the lower unit into reverse and forward with no problems. I also removed the upper unit and cleared out all the nastiness in the space around the end of the lower shift cable. I also removed the lower shift cable from the engine and with the engine running I mannually pulled the cable. It moved good, and netral and forward were no problem, but I couldn't hit reverse. <br />Could my lower shift cable be in need of replacement? Could there be some play in the linkage between the end of the cable at the transome and the lower unit?<br /><br />Thanks<br />Brian
