I have a 1983 35HP Evinrude which I need to remove lower unit to replace seals and water pump. I have the unit separated about 4 inches and is hung up on shift linkage. I have separated linkage from lower unit bottom but it does not slide past the water pump housing. I can not find out where to separate shift linkage from the top half of motor. My old 70HP was under carburetor. Where do you separate the linkage on the 35 HP? Any assistance would be appreciated.
