I have an old 1972 Searay with an inline six 165 Mercruiser. A couple of years ago I replaced the original drive with a Sterndrive Engineering SE106. I have had this drive on for a couple of years and it has worked fine till now. Recently I have been having problems shifting - especially in reverse. So I figured it was time for a new shift cable.
This is where it gets odd.
I pulled the drive and decided to go ahead and put an impeller in while I had it off. Before pulling shift cable I checked it and discovered that it was routed wrong - after rerouting it seemed to move smoothly, so I went ahead and reinstalled the drive to check it before getting new cable.
I installed the outdrive back on the boat, but now have no reverse.
Even when I disconnect the shift cable and pull on the cable by hand, it will not go into reverse. Spinning the prop clockwise it ALMOST seems to want to catch, but does not. Goes into forward with no problem, prop locks counter clockwise. Cable operates smoothly.
When I pull the outdrive off the boat, it will shift into both forward and reverse with no problems.
My first thought was that I had the intermediate shift shaft off by a tooth. I pull the drive off again and put the drive in forward and the shift shaft is pointing straight ahead. It is dead on at the straight 12:00 position.
I double checked the shift cable slide and cavity. No obstructions there. The cable pulls smoothly all the way in.
Reinstall the drive. Same thing. No reverse. It seems that the shift shoe will not turn far enough to get the unit to go into reverse. It is CLOSE - but not quite there.
I did a search of the forum and other sites, and did a test of the movement on the shift shaft to see if the shift spool might be worn....
