My motor is slipping out of forward gear. I have disconnected the gear shift cable and held the shift lever in the forward position while running                                                                                                                                                         and I have nothing. I take the motor out of the water and check the gears and they work fine  by hand. It seems it only slips out under a load. I have recently changed my impeller (ie disconnected my shift rod linkage)but there is only one way to put it back together with the screws on the connector going through the slots in the shift rods. I have just pulled the lower end and  everything appears to be ok, although I don’t understand the function of the retaining ring (part 37). before I opened the lower end I shifted the gears by hand using the shift rod and it shifted very easily, to me it was too easy. I’m used to a little resistance shifting gears. Some of the older models have a piece of medal in. the lower end that causes the shift rod to stick on various positions, but this motor does not have that feature. Is there any adjustment on the shift rod other than the adjustment on the cable? Can you guys give me some answers. Thanks
