I have an 89 Evinrude 150 VRO. After a dozen or so weekends of repair and cleanup I put the boat in the water for a test drive. She started right up and idoled great. After a few minutes I tried to put into reverse but couldn't get it in. I tried foward...no luck. I know that I issue is not in the cable. I can see that when we push the the control lever it is trying to move the shift linkage but it won't budge. Any suggestions. I can't find anything in the manual.<br />Thanks,
