Some years ago my lower unit failed. I bought a whole used outdrive and installed it. I think the cable at the lower unit was not properly installed. Up top at the shift converter box the control arm is way too far clockwise in reverse. So I'll have to disconnect the cable at the converter box and remove the retainer on the transom. Now if I can push/pull enough slack in the cable, can I get the lower unit off or lowered to get in there and disengage from the rack and make the cable the right length? I've heard to use lube for moving or inserting the cable. What type of lube? I don't want to use something that might eat at the cable covering.
