Default No Fire on a 540's

I have tried everything I can think of. I have no fire to the distributor, I thought maybe it was a bad kill switch, but that checked out ok. I replaced the coil, the plugs etc., I even checked the air in the tires. Please help.

If it has MSD, the box will be junk.

Start with a 12 volt test light and see if you have power to the ignition module first.

Have you ever had any voltage issues with your boat? If you have an MSD and run the ignition on less than 12 volts you can screw the ignition up.

If you have MSD. Swap the box from your other motor. or borrow one. One day it will fire, next day its a new Anchor. That's how one of my boxes went.

I don't have an MSD box on either motor. I just have an MSD coil, that I just replaced, with no luck. The only thing I did electrically, was install a new breaker on the fuel gauge. I unplugged the breaker and still no fire. It first started out on one motor, no neither motor will start...

if you have an MSD and try to run it on ANY voltage , the chances are good it will fail.

Have you run a test lead on the positive side of the coil to see if you're getting power when the ignition is on? Also, while cranking put a test light on the negative coil wire and see if the light flickers.

Takes less than 5 minutes to verify this, then we can go from there.

Blower motors with carbs, msd coil, reg. ignition. Motors crank only. Nothing is unplugged. All breakers are in good shape and operating correctly.
