Mercury 4 hp Gnat shifting adjustment

I have a 1978 Merc Model 40, 4 hp Gnat outboard, (twin cyl.). These outboards were only made for a few years due to a number of factors including an inability to siphon. There was no fuel pump, the carb had to suck in the fuel thru a lower shutoff valve. I re designed the fuel flow to give a direct positive fuel flow with a clear fuel line ( so I can see if there are any air bubbles) and now it runs fine.
Problem: I can't easily get it into neutral. It starts fine in gear but I'd prefer to start it in neutral. Can anyone remember how to do this adjustment?
Thanks, Larry
 
I have the 1977 4 HP twin. S/N 9320599. Made in Belgium. Mine is stuck in gear. I took the lower assembly all apart and I think it has something to do with the gear rod at the bottom. I wish I could find parts for this. If anyone could help, that would be great
 
Our son got it figured out, he put a coat hanger in the the lower leg shift shaft hole, turned driveshaft until felt a restriction (stop).
Installed leg on motor in neutral, moving flywheel ever so slightly until driveshaft lines up with crank. Did it a few times, lowered and works fine.
Notice when put it in neutral takes 1/2-3/4 revolution Before disengages. Best of luck. Yes parts are extremely hard to find. Ask mercury dealer to look internal access to what dealers have, different than online. Also some Mercruiser guys have a boneyard of parts to pick from. Paying 40 buck for a float bowl Jet/bolt. 1395-6043, ouch !
