Engine wont start all the sudden

[spareparts]

purple is key on power, see if you can find the one going in the main harness to the engine, it may have been conected on one of the gauges, look for the engine harness, it should be sepaerate from thr boat harness

Maybe a dumb question... if there was no power, would the engine turn over? Because it is turning over...

In any event, Ill look tomorrow morning! Thanks!

Turning the key to the first position (Run) energizes the power to the run circuit to the engine. Turning the key to the second position (Start) energizes power to the starter solenoid, that then pulls in the contacts sending power to the starter motor. The two circuits, although run off the same key, are actually different and yes, the engine can turn over without starting.

turning over supplies power to the yellow/red wire, red is constant power from the battery

First I would listen to the heavy hitters here they know there stuff , but sometimes you need an outsider, first I wouldn't get to complicated ,what I would do is
Hit it with starter fluid, whitch you did and it did not start Ok next
Check for spark, do you have it? I don't think you do
If you don't since it's an inboard , check or replace the module on the distributor
3 things you need Air Spark Gas And power to turn the motor
You got air?
You got gas going to the engine? Could be a bad fuel pump
You know you have power
Spark , Check that
Good luck

Thank you for the qudos Steplift, but my knowledge pales in comparison to SpareParts and TheFermanator. In fact, they are the ones I go to when I need an answer. They're the *real* heavy hitters... I'm just Junior Varsity compared to them.

Engines are pretty simple. They need fuel, spark, and compression. If you have all 3, it should run barring that they are all happening in the right order. 1st order of business is to check for spark since you've already tried starting fluid. Just going to have to work at it 1 step at a time.

Well, I posted this problem and went on a quick working vaca to upstate NY. I'm back, and it was bothering me yesterday - it ended up being the purple wire running from the ignition to the engine. Power for the starter was fine. Unhook the purple wire, hook up a bypass to the engine and bam, started nicely. Now to rewire the new purple wire...
