newbee lower unit questions-> 1965 Merucry 350 -> binding & shift linkage questions
1965 Mercury 350 - 35hp
Serial#1900802

I am having difficulties removing lower unit from the rest of the motor (to rebuild waterpump/service impeller); it seems to be binding on the sides of the waterpump housing.
I have removed the four nuts, trim tab, attempted to ?remove shift lever coupler?(more below) and pryed it about 1/4? apart with a flat pry bar. (very carefully)
I have the Sealock manual(Vol 1): It says for ?Older units? (pre 87) ?Remove the shift lever coupler located in the bottom cowling behind the carburetor.? No picture(of course).
I don't see any sort of fastener or C-Clip holding the shift shaft to ?shift lever coupler? under the carb....I have disconnected the two pins (w/cotter pins) that connect the two adjustable linkage rods that run from the ?shift lever coupler? to the shifter cable and the other linkage that keys into the throttle.
With the two rods above disconnected, I can wiggle the shift shaft up and down 1/8?to 1/4?. (I think that's good news?) Since they say ?Remove? in the manual, I am not sure if I got it right, since the ?shift lever coupler? hasn't really gone anywhere. The only other thing it looks like I could remove would be the spring clip that holds it in gear, but that looks like it will be a SOB to get at the bolt and get it lined back up, so I haven't gone there yet.
Is it possible for the original waterpump cover(47ish years old), if it's plastic, for it to have swelled and that is now causing interference during disassembly? (I know nylon tends to absorb water...)
Carefully keep prying? When I apply pressure, the front and back seem to be looser that the middle
Anyone know what kind of plastic they used on these originally? (assuming it is plastic)
If anyone has ever run across this problem before, any help would be greatly appreciated.
Thanks for taking time to read my rambling ?.
