I bought this boat not running. The guy ran it a few years ago and winterized it when spring rolled around again it would not crank. It has no fire, what should I check? How do you test the electrical box?
 
Be sure it has a new battery and a full charge on it. Also check the wire connections at the battery posts, and the ground wire going to the engine by the starter area should be clean and getting a good connection as well.

If all your connections are good and your battery is good, check to make sure you're getting voltage to the starter. Are you hearing the solonoid click? Only reason I bring this up is that I am currently rebuilding my starter, after the brushes went inside it. My solonoid clicked and I had 12 volts at the starter, so that's how I found it. Kind of a pain with the starter being under the exhaust (on my boat at least) but only a few bolts to get to it.
 
Ok, when you said it wouldn't crank, that's a starter sounding problem. No spark, only thing I can think of is to test the coil, but I'm unsure on how to do that. Make sure all fuses are good, and find out how to check the coil, you might be in business.
 
Mpem....

This is the first year of the DESS (digital electronic security system). When you connect your lanyard, do you get two beeps? If not, leave the lanyard off your post, push the start/stop button on one engine, 5 times. You should hear one long, one short beep. Then, put the lanyard on the post. How many beeps did you hear. IF you heard none, then you should be able to start.

If you still have no fire, check your fuses.

How do you know you don't have fire to the spark plugs? Did you actually ground a plug to the engine block and turn the engine over?

This boat, with the twin 717cc engines uses the CDI ignition system with a primary and secondary set of windings. If your magneto is not generating the power for your CDI, you'll have no spark. If your maneto is generating the power but one of the windings is shot, you won't get spark.

A defective speed limiter will create a no spark issue. To find out if the speed limiter is causing your no spark issue, disconnect the BLACK/RED/GREEN wires from the magneto system. If you have spark, then the speed limiter is your problem.

There is not much you can do to test your electrical system because it requires the BRP ignition tester but you can check the resistance on your generating coil output. At the magneto, if you can determine your black wire and your black/red wire, you can test the resistance on it. You should get a reading somewhere between 40-76 ohms.......

The worse part of these systems, even if a coil tests good, it does not mean it isn't still faulty.

Your problem could be in your MPEM, magneto or coil.........so, this is going to be a difficult process to trouleshoot without the proper tools.......
