The OMC solution for a loose stator plate I was referring to.

Bosunsmate, lol, I was one of this people when I had a 58 Fastwin. Had extra everything coils,points, plugs and flywheel keys.

Struth i wish i was that studious! I do take a full tool kit in my 4x4 which makes for peace of mind on the road too, I can pretty much drop out everything on the roadside if needs be which has included a diff in winter, maybe i should also pack a chain lift, those diffs a heavy.

I've gotta to old to keep things in vechile. I just call roadside assistance now! lol

haha hopefully you would still change your own tyre, where i live the guy is too old and grumpy and thats if you can get cell phone coverage.
Boat assistance here is really pricey too, but i keep a spare outboard tied up under the bow and also i try not to be the furthest boat out!

So I have the lower unit all re-sealed. The coils came in and barely tested any different. But I installed them. The #1 cylinder sparks 1-2 times in one strong pull of the cord. #2 cylinder sparks 1 time on a pull and occasionally not at all. I figured it was where the flywheel starts on that pull. But is this a big issue?
I'm still not tapping 7/16 but I'm close. Maybe a mm smaller gap...

I'm seriously considering opening the ignition again.
When I set points they looked newer like everything on the motor. I cleaned with 150 grit sand paper and used rubbing alcohol after. It seems this is a pretty bad method but I couldn't imagine it to be all that horrible??
I'm so tired of this thing I've barely worked on it lately.?
Thanks

 

[Bosunsmate]

Hows it running now? and have you tried a cylinder drop test?

 

[brsoo]

I haven't tried that. With the old coils it would likely pull out the plug wire. Ill run it today and try that. What do you use? A wrench? Thick gloves?

Ok so I decided while I was still waiting on my gas tank (old one stopped showing fuel level). I decided to dig into the ignition system again. I checked the timing with a vom like what another guy did on YouTube. He learned this through iboats btw! I've watched the video before and figured that probably wasn't my issue. Well I checked it and it seemed pretty far off. So I decided to redo all of it. I took off the armature plate and cleaned everything. That really helped minimize the side to side play in the plate. And I feel this could be part of my timing issue.
Then I cleaned and set points and checked it again. My .20 feeler was setting the timing off. I ended up checking the timing and moving the screw with out the feeler gauge. I'm pretty sure the feeler gauge would have been at .25 with it set right. Idk how or why??!??!?? I tested right after and it jumped a 7/16 gap for the first time also!
I did zip tie my plate to the throttle so it wouldn't move and would be set as close to idle as possible.. Does this make any sense???
Well the motor actually idles pretty well now. I think its pretty darn close to perfect. It does not stall out. It revs up and down fine. Sounds smooth very smooth. I can shift in gear with it at a pretty low idle.

I am having a lot of smoke tho!
It also still starts with no choke. Are these signs of rich mixture? I'm about 1-1/2 turns out on my needle...

Also I'm still getting gross oil like goop In my test tank. Is that old LU oil flushing from my cooling system? Or can it be rich mixture? Or do grease points in the steering sometimes spew out??

I am pretty dag on confident that its not my LU after that in depth reseal I did....

Thank you guys! I know ill be on the water shortly here

Here is the goop in my test tank

Also a couple of my armature plate. Do y'all know why it moves? Its like my tiller throttle is delayed going either direction..

 

[Bosunsmate]

Two strokes do make a mess in the water, you can see why some places restrict their use.
Go give your one a try on the water now it sounds much better

So I finally got to take it out on the water. I got it to idle really low in the test tank. So low that I could throttle all the way down and it wouldn't turn off. It would have to use the kill switch. Out on the water it would sputter out at low idle. So there is still something going on with it.

But this time it ran! I went around 20mph wot with two 150lb people and a 40lb dog. I think it should go about 25 mph wot. I'm thinking fine adjustments will help achieve this...
I was very very happy that it did as well as it did..

I noticed as it was running I BARELY had fuel if the fuel filter. It seemed to be starving itself. I'd pump the bulb and it would start to firm up. In going to remove the filter on Tuesday and see if it is the problem...

 

[brsoo]

So I just looked at the lower unit and it has goop spewing out of all the water holes. Idk wtf this is! I just resealed it! Would it have to be lower unit oil??

 

[Bosunsmate]

nope, check your gear oil level it might be residue from the exhaust

 

[brsoo]

Bosunsmate
I've come to the conclusion it is not gear oil. I feel very confident that the lower is sealed good. It seems to be exhausted based on the smell. I do not know why I have this issue tho.

Maybe fuel pump? Since it wasn't pumping well?

Vacuum leak? One of my vacuum hoses popped of while running before I zip tied it back. It comes out of the bypass cover which is also painted another color.

I have a couple days before family is in town. I'd LOVE to fix it so I can take out my nieces on it!

What tests can I perform? Thanks!

With a 2 stroke motor you mix oil in with the gas not all of the oil is burnt and it goes out with the exhaust. This is normal and is asked about here almost daily. A well tuned motor may produce less and if you run often at slow speed it may be worse. All your running in a test barrel you must of seen oily scum in the water?

 

[brsoo]

No Title

I get that. But man, there's a lot of gunk!
This is normal???
Am I mixing correctly?
Could the fuel pump cause this?
I mixed just over 5oz for 2 gallons of gas making a 50:1 ratio. Right???

Ok. So I worked on it just about all day. I found I have air in my fuel. A lot of air. Like moments that the whole line fills with air. After replacing most of the clamps I got it a bit better. But it still randomly pulls air. I can not locate it to one spot. It is certainly before the engine.
I'm sort of thinking its the evinrude fuel connector. I have a attwood line that came with clamps and connectors installed. Like it moves around and doesn't seem fully sealed. I've pulled it in every direction and can't seem to get any one spot in the line to consistently suck in air. It seems very random...

I'm very tempted to order a new omc fuel connector. Any advice on the best designs?

 

[Bosunsmate]

i got rid of the connector on my 60hp and just hooked the fuel line directly to the fuel pump by running the hose through where the connector was. That meant one less thing to go wrong and i just wrap the hose around the engine when i move it.
You may have a leak in your tank pick up area, thats not uncommon.

So I took it out yesterday. Ran GREAT at first. Loaded the 15' with 5 people! It pulled out and at wot went about 5mph. About what I expected for a overloaded boat and old ass motor.
With a couple people it ran pretty darn fast!
Went for two short spurts and then it stalled and died. The last run the bulb wasn't really hard so I pumped it while going still thinking maybe its got a fuel pump or air in line issue. After it died I tried EVERYTHING. Set the needle differently choked or not wouldn't start. I paddled all the way home with 900lbs probably. I have felt dead inside and out all day. I'm just so exhausted from this damn thing

Still leaks excessive amounts of goop out of the lower holes. I think there is something pretty wrong that is being ignored.

 

[Bosunsmate]

fuel bulb is never hard while running, just should be soft but not collapsed.
Look at your plugs, see if they a wet with too much fuel or what
