1GM throttle mechanism

Posted by fgljff (fgljff@…>)

I have a single lever for both my transmission and throttle. There is a button
in the base of
the lever. I’m assuming I pull the lever to put the engine in neutral. But the
button won’t
move. Is there something that I"m missing; a way of locking and unlocking the
bottom? Or
can I assume it’s simply stuck or frozen? Any tips?

You are right, the button in the base of the lever is to put the
engine in neutral. Mine broke off all together. To rev my engine in
the water I put it in reverse.
If you open the locker over the throttle controls you will find a
wooden box. I had to pry off the top to gain access to the controls. A
liberal amount of WD-40 might unlock the neutral knob. Since you are
not in the water right now you could rev in gear.

I used a penetrant and managed to get the thing loose, so I could get the engine
in neutral.
Engine started up, but there was barely any water/antifreeze spitting out the
back. I stopped
the engine, and checked the raw water strainer. As I suspected, it was all
frozen slush in the
basked. I poured antifreeze into the strainer, then put a heat gun on it. I’ll
try the engine
again tomorrow after leaving a small electric space heater in front of it all
night. Also,
tomorrow’s going up into the 40’s. Should solve the problem.

I hooked a hose directly to the pump on the front of the engine and
flushed the system with “Salt-Away”. Then I ran -40 deg F fluid
through the engine till it came out the back. I took the strainer
apart and blew out the hoses to and from the strainer to ensure there
is no water trapped anywhere

So you bypassed the raw water strainer? In retrospect, I probably would have
been better off
doing that. How did you blow the lines clean? Did you fill the strainer with
anti-freeze?
