mercruiser 170 224 ignition help

would anybody know if this engine uses a ballast resistor or not. also is there a way to give gas to the engine while in neutral like in a car when the engine has trouble starting and you just pump the gas. i'm just new at this, if someone can help...Thanks
it's a mercruiser 1985 170 3.7L engine.

 

is there someone that can help..thanks

 

if you have pionts yes you did have a ballast
yes you can give neutral throttle but ? what control box do you have

 

figured out the controls. but where would the ballast be and what does it look like..thanks
