I have a mid 80's, I presume, 28 HP Johnson SPL, the model and serial number are worn from the tag. Issue is trying to disconnect the linkage to remove the lower end to change impeller. There are 2 removable peices to the lower end, the lowest piece , which includes the prop, and a piece just above it that is about 8 inches long, it's almost like a spacer piece, which connect to the bottom of the exhaust housing. I can disconnect each of these parts, from each other, and the top one from the exhaust housing, but there's no linkage disconnect between them, and not much room to work either, maybe 3/4 inch. Is the disconnect for this engine in the motor housing, behind and below the carb? It seems like on this engine, the starter would have to be removed in order to remove the carb (what a pain). There's also only one water intake screen, and it's near the bottom of the lower end, so no linkage disconnect there either. Any help would be appreciated.
