Is this the right part? Does the spark plug wire need to be replaced or does it detach from the old coil?

Which brand is best?

Ok Guys I found the culprit I think. Looks like the coil is busted, I spark tested the top cylinder and no spark, spark tested the second, spark.

Then bassboy reminded me that he may have saw something when he was looking at the motor but it just slipped his mind, well I looked and I found this.

Where can i order this part?


Bassboy has a good eye. Yes that coil is cracked. Hopefully once you replace the coil, you will be in business. Quick cheap fix....hopefully.....I've got my fingers crossed for ya buddy!!!

Got this one.

if you matched up the year and make of motor...then you should be fine :)
 
More Issues:

So i changeed out the coil and there is still no spark to that plug. I have by process of elimination figured out where the problem is I just dont know where to go from here.

The wires with the blue tape go to the "bad plug". I mixed and matched the wires to both coils and the problem is the blue wire set that runs to the magneto/flywheel. The top coil will work when I use it with either of the lower wire inputs, but will not fire with the blue tape top wire input that goes to the flywheel magneto.

How do you get the flywheel off to set the points? I fear that may be my problem. I tried to unscrew the bolt on the top of the flywheel but it wont budge. About to take this thing to a competent mechanic if all else fails.

Pics below.

ANY ADVICE?

Wow - I didnt realize what it takes to get that fly wheel off. I fear my problem is the coil under the flywheel but you have to get a breaker bar and all kind of stuff to access the innards and I dont think I am capable. On to the marine shop.

Niether of which that I have. I dont know of a good marine mechanic either so I am kinda lost about what to do.
 
Here is a link that describes the tools and things you need to remove your flywheel and clean and adjust your point.

It is an Iboats.com forum link, so in order to see the pictures for the tutorial then you will have sign up for the site just like this one (free). Please, I am not steering you to another site, but the tutorial is good and it has pictures as well.

https://forums.iboats.com/showthread.php?t=294072 (points, coils, condenser and flywheel)

https://forums.iboats.com/showthread.php?t=338579 (more information on flywheel removal)

The link gives information on how clean and adjust the points.

re-torque setting of the flywheel nut is 40 to 45 foot pounds.

Here is link to a free site with a condense manual for your motor---follow the instruction to navigate through the site.

I do. If you can hold off until later in the week, when I can get this current boat finished, I'll help you get that done, and we can take my rig over to the river, and see about finding some stripers.

I think I may have missed a few of your emails - I've been getting about 4 hours of sleep the past few nights in order to get this rig done, and haven't really had the chance to check my email.

Thanks Buddy. I know that G3 has ben keeping you busy, thats why I didnt want to bother you asking you for help. I found a guy right down the road from my house that said he could do it no problem. Hopefully it doesnt cost me too much, but I am to the point now that I dont want to waste any more time off the water. I had to go to Tribble Mill yesterday because my motor was out and Im not sure how many more times I can stomach that grass bayou.

Once up and running I would love to get on that river and need to get you out on Lanier for some trolling and live bait fishing. I went and picked up that bait tank for nearly nothing and it looks like it should work well. I have started painting it white to counteract that dark blue for heat purposes.

See ya soon.
