I have two almost identical 1980 Johnson 9.9's. One is a short shaft, the other is a Sailmaster (longshaft). <br />Dropped lower unit on both to inspect water pumps. <br />Now having problems with reattaching the lower units to the powerhead. <br />Problem is the shift linkage. When I removed the lower unit, I placed the shift arm in "Forward" to expose the linkage screw. What is the secret for proper shift operation when reinstalling? The screw is only accessible when the gearcase is in "Reverse". The upper shift linkage is only long enough when shift arm is in "Forward".
