Not starting

[SkiBoy]

Got my new plugs, gapped them and installed. Put a slow charge on the battery, took the ignition switch out and went into town. No luck. The only marine model had different connectors. Went online ordered a Sierra marine 3 position that is an exact match for mine with red, purple and yellow/red wires. There is rust on the old switch, so there must be some inside as well. Put some dielectric grease on the connectors tapped it several times, reinstalled it and the boat fired up. New ignition will make me much happier.

Will report back. Thanks

Awesome! Maybe that got your mystery problem solved!!

Installed the new ignition, and running great. As a bonus I now have a spare key.

Thanks to all who chimed in.

Glad you got it back up!

No spark again this morning ran great started like it is injected for two weeks. Today no spark. It sat for two days, so I primed the carb with a couple of drops to start, and nothing. There is a reset button where the main power from battery goes. Seems fine. I am never going to trust it to start again at this point.....

Man, that has to be frustrating! Check your switch connection plugs again since you had them apart when you changed the ignition switch out. Maybe something is not seated all the way.

Checked all connections to the new switch. Will try to trace the battery wire tomorrow. Everything looks good and feels tight. If I ran a new wire, can I go directly to the battery, or is that not advisable?

Did you determine the no spark to be coil to distributor, or distributor to plugs?

Just curious where the problem is starting.

I am just assuming it's the same problem as last time. No spark getting to the plugs. Will try and figure it out this weekend.

Coil is new
Plugs are new or at least good
Wires are good
Connections all tight
Fuses/breakers good nothing tripped

Battery ran for 2 weeks assumed good

Can you check the connection from distributor to the coil? Seems like the distributor is not signaling the coil to fire. The pickup in the distributor could be flaking out on you. Or a bad ground plane on the engine. A loose ground bolt/screw, or lose terminal crimp can cause this also.

Check the connector at the distributor has some flake wires or bad connection.

Also, neutral safety switch on the throttle. It will keep 12V from getting to the coil. Boats thinks it isn't in neutral and won't start. If you use the bypass button and move your throttle forward slightly you can attempt to start the boat. If it starts then the neutral switch is bad.
