I need to run my 175 HP black Maxx on my engine stand. I only want to idle it with muffs on it. I don't want to remove the control box and cables from the boat. I can place it in neutral and choke it manually. What is the safe way to wire it up?
Heavy red cable to the post on the solenoid... Heavy black cable to engine ground.
That is all you need.
To start it just momentarily short the red battery lead to the start terminal (yellow/red) on the solenoid. To stop it short the 'kill' wire (black/yellow) to ground....

It's the centre post on each of the switchboxes. Also the mercury tilt switch if your engine has one...
