I ohm tested my ignition coil using the manual 2Valve sent me and my ignition coil failed the test. This is great news! Replacing this should fix my no spark issue! I'll keep everybody posted when my coil gets in! Thanks for everyone's help!

Which two pins do I need to OHM out together? The two top ones or one top one one bottom one? I tried to find a diagram on this particular coil but have struggled. Is the top connector the primary in the bottom of the secondary or?

Of course I'm aware that some diesels have ignition timing for the injection pump. It's just not the same. I have never messed with a gas engine before. At least not doing timing. Not all diesels have injection pumps that are driven off the camshaft though. Like for instance, the 7.3 L international found in the '99-03 Fords. It has a cam sensor. No timing to set. Just plug the sensor in. I was just trying to not go into details about it because it wasn't important. But anyway I'm getting off topic. ? I've got it figured out now thanks to y'all! Thank you all for your help. Maybe after all this I will know a decent bit more about timing on a gas engine. I will report back when the ignition coil comes in on if that was the problem or not. Wish me luck!

I'm kind of confused by the very first part of your comment. Are you saying the motor does not have to be at top dead center to change out the distributor? You can just pull it out at any point? Just make sure you have a reference point so you can put it back in the same spot? Also, I know absolutely nothing about timing.? Diesels don't have that..... I believe my dad knows how to set timing though so I will talk to him. Thank you for your help!

Also put a hot battery in it today as well. Previously I had to have my truck constantly running hooked up to it to crank the boat over. That is not a problem anymore.

Well, I installed the new distributor cap and rotor today. Still no spark at the plugs or coming out of the ignition coil. I believe I have diagnosed a bad ignition coil. But I would like to maybe replace the distributor anyway. Couple of questions. What brand is safe/trustworthy? How do you go about replacing the distributor? I watched a vid and from what I see, you have to have the motor at top dead center on cylinder one, put a mark on the block where the rotor is pointing, loosen the 1 hold down bolt, pull the distributor out letting it rotate counterclockwise, and install the new one in the same spot so that the rotor ends up pointing at the mark on the block. Is that really all there is to it? The video I watched he just put a screwdriver in the driver side front cylinder (cylinder 1 on sbc's) and had somebody bump the starter over until the screwdriver was all the way at the top. But, he did not go in depth about if it needs to be at true top dead center on a compression stroke or if the piston on cylinder one just needs to be at the top. Again, I know I've said it's a few times but this is new to me. The world of diesel is completely different so I may sound like an idiot but I'm hoping to be called out if so! Thanks in advance!

I tested the pickup coil, checked out good. I have voltage at the ignition coil. Unfortunately, the broken bolt is in a tough spot to get to. If I remove the crossover line for the fuel injection rails, I might have enough room for a drill. Not sure. Definitely not any room for vice grips. Not a chance. I do have an idea though. There is another hole directly beside the one with the broken screw that is just like the one with the broke off screw in it. It's for the centering pins on the distributor cap. I could get another bolt just like the one that broke off and thread it into that hole after making a small hole in the distributor cap right where the centering pins is. There's plenty of plastic flange there to drill on. Of course this will be a last resort. Going to try not to have to do that But it's better than replacing the whole distributor. I have been talking about with a kind member named 2Valve. He wrote a bit of a manual on how to diagnose fire on these engines and I have been on the phone while he talked me through my tests. The only thing that didn't check out 100% from what I understand is the switching wire that is supposed to be feeding the fluctuating pick up coil voltage to the ignition coil. The wires that do this are definitely getting voltage but I cannot tell if it is a pulsating voltage like it should be because I'm not using LED test light I'm using a incandescent bulb test light so the light just stays on. If I understand correctly, the switching wire from the pickup coil should be pulsing on and off with the engine turning over. Here is a link to the video. He recommended LED so maybe that is why mine is not pulsing. https://photos.app.goo.gl/EgSdSyWZDc2EuGp76

I took my distributor cap off. It looks terrible. Corrosion all over. Looks nasty. And of course as per usual when doing any mechanic work on an older engine, the hardest to get to distributor cap bolt broke. Not sure how in the heck I'm going to get that out.

I retract my previous statement. There is voltage at the ignition coil. Turns out the wire has to be plugged in to have voltage lol.

Okay so broken governor. Not a big deal right now. I need the thing to run before I mess with that. I tested for voltage at the ignition coil. The wire that is supposed to received voltage is not receiving anything. I'm trying to take my Cannon plug off so that I can inspect it but it is so seized that it will not come off. For some reason there was a hose clamp on the plug itself holding it for some reason and I cannot get it to come off yet. Any tips and tricks? I took a pic and loosened up the rubber seal that had been created from the hose clamp squishing it. It is still just seized in there.

As stated earlier I am a diesel mechanic. Never worked on a boat before. I got the boat for a really good price and I am completely unfamiliar with anything to do with ski boats. I don't know much of anything about their electrical system. The plate is on said ignition protection so I just assumed it was some sort of safety switch. I guess I should also put out there that I only just turned the 19, I'm still young and have not had the experience of working on all different kinds of things yet. But, after I bought a diesel truck and had to work on it myself and learn how to fix it, that spiraled into me working on a lot of diesels. However when it comes to a boat this is the first. I don't really have a expendable income to spend a whole lot of money on a boat but I got a really good deal on it. I mean a stupid good deal. It probably hurt your feelings if I told you how cheap I got this boat. They cleaned up really nicely too. Aside from being a diesel mechanic I also have a lawn business, I do tree work and I have a job at a shop as a small engine mechanic. I have worked on quite a few vehicles and have dealt with my fair share of electrical issues but, I know nothing about what type of safety switches a boat would have. Nor do I have a wiring schematic on the wiring on this particular boat. So no, I do not know anything about the perfect past system on this boat except I know that it has cruise control and is designed to help skiers / boat drivers to make it easier to do certain things while skiing like, doing loops around the boat or something similar. I know nothing about water skiing either. Hoping to take my family tubing with this boat. Might get some water skis at some point. All of that being said, I was hoping everybody on here could help me learn more about these books which all are doing a fantastic job of so far! And I am very appreciative to have your help! You have my gratitude! Sorry I wrote an essay LOL

That makes so much more sense! The only reason I thought it was a safety of any sort was because it said ignition protection verified or something similar on the front plate. You know now that I think about it, I was having some issues with every now and again the key wouldn't do anything and I would have to bump the key a few times to get it to turn over. I need to check that Canon plug like previously mentioned. After that probably an ignition switch. And so on so forth. I tried to use that website but, it appears I already have an account and I do not know the password and I tried resetting it but never got the reset email. I will try again! Thank you so much for your help!

What is the cannon plug? I am a diesel mechanic and I'm not very good with gas engines or electrical problems associated with how a gas engine works. Thank you.
