So I’ve tested a bunch of stuff but I totally suck at electrical crap, I still have no spark and I’m desperate to get this thing going, it’s a beautiful boat for a 1997, I’m looking at 3 different MPEM for my speedster on eBay but they all about $1200, I’d really like to be more sure before dropping that kind of money
I did the disconnecting rev limit wires from stator but got nothing, if I get 2 beeps when connecting the dess does that mean it’s bad?

What do I do?
 
2 beeps is good

Put a 12v led in the line going to the coil. Does it blink when you crank? If so it's the external coil (with the big wires going to the spark plugs inside the electrical box)

Did it flood recently? Did you open the black electrical boxes where the coil is? Is the box dry?

I might be a bad stator or pick up

The service manuals can be found online for cheap.

What engine on it? Twin 717s?
