super dave

Thanks fisherman. I'll take a look

An update. There are 2 lines coming from the power pack to the coils. I decided to put one the line going to the coil that is not sparking to the good coil and there is no spark. So now I think it's either a power pack issue or stator or something else. Looks like I need to research further.

So I got it out but at the expense of the plug wire. So I'm doing an ohm test on the coil. On the Positive and neg posts I'm getting 0.7. From negative to the coil socket I'm getting 962. Looks like I should be getting 1280 to 1480. So is this coil junk? Sorry for all the questions. Really appreciate the feedback. Just try g to learn here

Here's a picture with the cracked coil. From what I've seen the coil and the spark plug wire are 2 separate pieces. Thanks for anyone that can help.

Thanks for the replies. So looks like I'll have to get a new coil. Still can't figure out how to remove the spark plus wire from the coil. Any thoughts? Am I just not yanking hard enough? Thanks.

Hey guys. I recently picked up a 90s Merc as another motor project to pass the time with this covid. I knew it wasn't running, great. Hard to start and if it did it would misfire and studder. Changed up the carb gaskets, needle, float(had some gas in it). Thought it was the float was being weighed down so it was not getting right amount of fuel. Diaphragm was a bit stiff and the plunger was leaking gas. So all that was changed but still won't start. Checked for spark again and the top cylinder no longer has spark. I guess it was going which could explain the misfire. Had it running good at one time but it just cut out with no warning so I'm assuming the spark cut out at that point. So looking for a bit of help for any of you Merc owners. I want to om test the spark wire but I can not for the life of me figure out how to get it out of the ignition coil. Johnson's are much easier. I also noticed the lip of the coil where the spark plug wire attaches to is cracked and a small piece of off. Would that affect spark? Any suggestions? Electrical is new to me. All my past issues have mostly been gas related. So any tips would be appreciated. Thank you in advance

So did a marvel mystery oil treatment on the top cylinder and I'm getting about 112 psi in that cylinder now. 😁 Just put some in cylinder 2 and let's see how it goes. Haven't started it up again so I'll update tomorrow. Thanks for all the help from everyone. Hopefully this thread will come in handy for someone else.

Thanks old man. Was trying to figure out how to get the recoil off. This helps a lot

Hi dan Thanks for the suggestion. I did do that with new gas and the issue was still there. I think it is a compression issue as Dave stated. it doesn't have enough suction to pump up gas even with the choke on. I was getting about 70 per cylinder and doing something to address that now. I noticed the flap that closes when the choke is on, has a few holes so I plugged up the carb vent with a shop towel and it started by the second pull. Appreciate all the input from everyone.

Hmmm. Not with the throttle open. At least 5 yes. I'll try again. Thanks all. This is my new covid hobby. Buying broken engines and trying to fix them. If this is junk I can at least get rid of it for parts or I'm out 300 bucks. Not a big deal. But would like to get it in good running shape. I figure best way to learn small engines is to actually do the work.

Update. Compression is low. I'm getting around 70 psi in both cylinders. I got some marvel mystery oil hoping it will free up the rings. I can hear air escaping somewhere in the prop area to confirm the low compression. Once I dump the oil in the cylinders, what position should I be resting the motor to allow it to soak?

Makes sense. Thanks.

Hey Dave. I'm assuming if it's reeds compression would be low? There are no other symptoms of bad reeds.

I do. I should test that. But it starts extremely easily after I get it going. So starting again isn't an issue just first start. Thanks for your input old man. If you have any other ideas I'm all ears.

Primer bulb works. I took off the gas line to the carb and it shoots gas when I pump it. I can smell gas after pulling with the choke on. After it starts I can start it by just half pulling at a much slower speed.

So I tried starting it with a long rope wrapped around the fly wheel and it worked. My theory is the starter rope is too short. Does that make sense? I can see that the rope is too short to wind on all the thingy. I attached a pic. Fully extended the rope is 36 inches long. Should it be longer? I thought I read it should be 54 but my arms are not that long.

Hey guys. Got another outboard question. I picked up a 6hp Evinrude early 90s. It just won't initially start. If I give a little squirt of carb cleaner or starter fluid in the carb starts right up and stays running. Idles perfect and revs great. Then starting is no issue. It's when I leave over night it won't start again. Need to shoot a bit of fluid in the carb to get it going then no issues again. Fuel pump is working. I took off the hose to the carb and it's pumping gas when it's running. Any ideas? I will clean the carbs but just weird how it runs great after it gets going.

what about an aluminum brazing rod? it creates a pretty strong bond to the aluminum. might solve your crack issue. just make sure you use MAP gas instead of propane. Propane will not get it hot enough to melt the brazing rod, especially on a big boat.

Thanks to all that replied. Your advice is very appreciated. I attached a vid of it running. It's a bit Smokey but I'm assuming that's the fogging oil. It hesitates for a second at the end but that's the bare wires of the kill touching. Thank you again! 20200514_184559.mp4

Oldman. I owe you. I guess the idle screw was turned all up. Tried it quick without water and it sounded great. Tomorrow I'll put it to the test in water. Thank you!!

Thank you gents. I'll give the carb screws a try.

Hey guys. I picked up a used outboard and everything seemed ok on it. Started up looks clean. Tested it at home and it runs fine but then after about 20 seconds it revs up super high in idle. Almost like the throttle is opened up fully. If I turn the throttle it will rev up a bit more. Any thoughts on what it could be? It's a 2000 8hp johnson

Duped the topic by mistake

Thanks OF. I'll take a look at the link. Watch a lot of danger marine vids too.

Hey BC. That's great. How can I get a hold of your son?
