I have a 1963 40 HP Big twin evinrude. Model 40352 on a 1959 richiline hull. This old motor fires up and runs (ran) like it was just built. The other day while waiting to exit a shallow dock my stern drifted into a hard packed mud bank, the prop dug in, and killed the engine. It restarted just fine.
Now when I shift the motor, reverse is reverse, neutral is neutral, BUT forward is also reverse. Where should i begin looking to correct the problem?
Last year: I replaced all the lower unit gears, clutch dog, bearings, shifter lever, prop shaft etc. with OEM parts because the clutch dog was worn and i found excess corrosion on some of the parts and its been running great. we use the boat at least 5 times a months. When i shift using the cables and the motor lever everything in externally functions properly, in neutral the prop spins freely, in gear it does not spin (by hand easily) in either direction .
Because it goes into reverse when you shift into forward, remove the side access cover to check for damage to shift rod and connector. If everything looks good, then it is time to tear into the gearcase innards and inspect the parts.
Be sure to check the propshaft for straightness also.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
Thank you Bluewaterbill. I opened the side port and the lever seemed connected even while manually shifting, but it like it was trying to get stuck in the lower end. I removed the lower gears then shifted again. The lever stayed seperated at the linkage and the lower pinion bearing fell apart. The tip of the shifting lever has screw thread type gashes on it. ( i assume from when it slipped out of the connector).
Ill be replacing the connector ( just for peace of mind) the lower shift lever, and the lower pinion bearing. Ive added what im doing for future 1963 owners. Its somewhat difficult to find information on these awsome engines. Thanks again Bluewaterbill, your advice helped out alot.
