1972 85HP Chrysler -- No Spark?

[turtle1173]

Hi all,<br /><br /> I just recently purchased the above engine (3 cyl and 3 carbs). The model # is: 857HD<br /><br /> The motor is very new looking and I got an exceptional deal on it. Plus it was delivered for free.<br /><br /> I finally got it and put it on my boat. It had been sitting indoors for probably 10 years. I knew all the basic stuff that would have to be done to get it into "useable" condition but my main concern right off is to make sure the ignition works. After that, then I can clean the carbs, replace impeller, and replace fuel pump. I decided to squirt some premix into each carb throat and try to start it that way. Is this a bad way to do it? Anyway it didn't work.<br /><br /> I took off the distributor and checked the points. All looked well with that. I made sure I put it back just like it came off (timing belt and flywheel marks).<br /><br /> Then I decided to use a spark tester. Of course it showed me what I already figured -- no spark.<br /><br /> So I got out my volt meter that I'm not very competent with. I am getting 12 volts to the CD module (blue wire). I checked the resistance on coil and it went about 3/4 of the way to the right. I'm not real good with ohms. The manual said to put it on Rx1 but I don't have that setting. So I put it on Rx10 and it went 3/4 the way over.<br /><br /> I'm figuring it is probably the CD module but I wanted to ask if there is a "sure way" to find out. Also, is there anything else I should try? This is probably the reason it has been sitting for 10 years. Then again, if I replace the module, I will have a "like new" engine (if that's the problem).<br /><br />Thanks,<br /><br />Shane

I currently have the same your motor and it runs quite well. MagnapowerI is reliable but Magnapower II is not good. Chrysler had problem with Magnapower II then a new kit was used to subsituted for MagnapowerII. No spark is common problem with Chrysler CD module. If your motor is magnapowerI, there are many good used part available. But if your is Magnapower II, you have to look for the replacement kit of it. I have one good used spare of 1972 MagnapowerI (I just keep as spare for my motor). Let me know if you are interested. With Chrysler outboards, you have to run it more often and run it hard. 1972 is good motor. Need a manual.

ChryslerOutboard,<br /><br /> I don't believe this is a Mag II. It is distributor driven with the CD module and coil externally mounted above the fuel pump. I believe the Mag II has everything under the flywheel (except the coils), right?<br /><br /> I'm glad to hear you say that this is a good motor. My compression on the #2 cylinder is slightly lower than the other two. I'm hoping it is just stuck rings since it's been sitting for 10 years. It's not real low (100 compared to 126 & 130) but not within the normal specs. Any thoughts on that?<br /><br /> How much would you take to part with your spare module? You can e-mail me at this address if you would prefer: shanewms@sheltonbbs.com<br /><br />Thanks,<br /><br />Shane

Hi Turtle 1173,<br /> I see on ebay an auction of "magnapower pack and coil taken from blown motor. stator looks burned do not know about rectifier. also includes selinoid and terminal board. fits most 4 cyls" now. Try this one. Be careful to make sure you get the CD power pack in working condition. I bought one before and it turned out "not working" you have no way to tell by the look unless you have a tester. It looks a good deal to me. Check it out. Go to ebay and search for Chrysler outboard

Hi again,<br /><br /> Yes, I had been looking at this auction. I e-mailed the guy about it and he told me that he had tested it and it worked. My main concern is regarding the fact that this is the original one that was on the motor. Most of the others that I am looking at are the "black box" units. The one on ebay is the gray with the words "MagnaPower Ignition" written on it. Maybe it is bad reasoning but it seems that the original might be more apt to go out sooner.<br /><br /> Am I just paranoid or does that make any sense?? Also, I have found a source to get a used CD module (the black box) for $165. Do you think that it would be worth the $40 extra to get the newer CD module or am I just worrying too much??<br /><br />Thanks,<br /><br />Shane
