Hi all, I'm at the end of my tether with a silly problem (ebay engine). I've got a nice clean yam made mariner (689 series) anyway, the original problem was it was jumping out of forward gear on minimal power, so I reset the remotes and tried again. Better but still jumping out of forward gear. More research and I thought it could be the clutch dog so stripped the gearbox and the clutch and gear had a slight rounding off the lead edge, I took it to the guys at ribs marine who said it didn't need replacing. So rebuild the gearbox and tested and all seems ok. Well, tried it tonight and same problem is there. I have increase the length of the gear shifter linkage (2 part) to the maximum I can get away with. The problem is better but its still jumping out of gear on throttle up and I have no more adjustment left. What am I missing? One thing I can't remember seeing though is the slide spring (no.37) when I did the strip out and rebuild.
