does my motor have an emergancy shut-off???

[sprouticus]

yesterday I went to the lake with my friend. Before we left, my friend had toppped up my second gas tank for my boat for me, while I ran an errand. We had a good time, and eventually ran out of gas on the first tank. Since I was currently behind the wheel when we ran out, my friend went to the back to change tanks. The engine started right up, and ran fine for about 3 minutes. then I noticed that we slowed down just slightly, and 30 secsonds later the engine just died. After trying to determine the problem, I discovered that my friend had not added oil to the tank after he filled it, and I never thought to ask him if he did. That meant that basically I was running the tank at 250-1 (or so). I added the oil, and turned the key, it started up, but would not idle fast, and I could not shift it into gear without it stalling. I started it up again and let it run for a good 5-10 minutes, eventualy the RPM,S picked up a little and I could shift it into gear and go home. It did not rev. very high however, but it was getting dark and I was afraid to turn the engine off in case I couldn't get it started again. Eventually we reached the ramp, and I decided to take another look under the bonnet. This is when I discovered that the spark plug wire on the bottom cylinder had come out of the coil,(a problem that I thought I had fixed, but I guess I didn't). Anyway, I twisted the plug wire back in the coil, started her up, and took it out for a quick burn. She ran fine.<br /><br />I apologize for the long post, and thank you for reading. These are my questions.......<br /><br />#1.) Does my motor (1977 70hp evinrude) have some sort of detecter that could tell that the fuel was too lean and shut the engine down???<br /><br />#2.) It was ran for a max. of 5 minutes at WOT with the leaned out fuel mixture. In your opinion (the reader) did I do any damage to my engine??<br /><br />#3.) What would you recomend using to hold that damn sparkplug wire into the coil...it used to come out all the time, till I siliconed it. THat lasted a little while, but what would be permanent??????<br /><br /><br />thanx again<br /><br /><br />p.s. iboats.com is great and I appreciate all the experts that come on here to help the newbies such as myself. If your ever in the neighborhood I'll buy you a beer

You might want to check the compression to see if you did any damage. Sounds like the plug wire coming loose may have saved your Bacon.<br /><br />Good luck

Thanx..I was planning on doing a compression check anyway, and I have already bought a new head gasket.........I need to get it out on the water again and make sure that it still goes the same speed as it used to at WOT.

Sprouticus> I will try to answer from what I have learned reading on this website.<br /> <br />I AM NOT AN OUTBOARD MECHANIC>>>NOR DO I PLAY ONE ON TV!<br /><br />#1-NOPE,<br /><br />#2-YES, the real question is how much damage>>>do the compression check before running the boat on the water>>>If one, or more cylinders are down, it could ruin the engine to run it hard if the rings/cylinder are scored.<br /><br />#3-If this is the pin type coil (High tension wire pushes onto a pin) check the pin to see if its bent over instead of penitrating the wire core. If it is, straighten the pin first. <br />I would cut the end of the wire & refit to the coil pin.<br /><br />GOOD LUCK<br />

thanx for the reply.i guess I havn't had a close look at the coil because usually the repairs are made while I am leaning out over the back of the boat in the middle of the lake I will make sure to do that tommorrow.

Re: does my motor have an emergancy shut-off???

ok.....i just did a compression check and it came out as 120, 118, 118. so I think I might have gotten lucky.....It is a pin type coil , but the plug wire won't stay on........I'm going to try silicon again it think. <br /><br />somebody please reasure me that my numbers on the compression check are ok...... <br /><br />thanx for reading

Comp. is OK>>><br />Have you tried cutting off a little bit of the plug wire before attaching it to the coil??? A fresh bit of wire at the connection, pushed on tight should hold. Use a pair of plyers to install and give a slight twist while pushing the wire into the coil>>>Make sure its seated all the way.<br />Good luck

Re: does my motor have an emergancy shut-off???

yes I tried that......tried it so many times I only have about 3 inches of wire left......lol....I just used a super strong type of loctite that I bought for a previous problem on it.will let you know if it works cause I'm about to take the boat out again.

Re: does my motor have an emergancy shut-off???

ok..the loctite didn't work...........I am going to try a glue gun next If that doesn't work I am out of ideas.

I've used small cable ties on spark plug boots with good results.

Re: does my motor have an emergancy shut-off???

i have no problem with the boot end.the problem is the wire will not stay in the coil................i'm thinking about changing the coil anyway...I did a test yesterday, and even though I did have spark..I don't think it was strong enough (couldn't jump that 7/16th gap)
