115 Yamaha trouble...

[brian1785]

My 2002 4 stroke wont turn over. Was up in LBDN this past weekend fishing and this morning couldnt get it to turn over. Cleaned the fuel filter but nothing. Tried heating up the tubes that run the water pump. Nothing. Anyone know of a good Yamaha dealer in N. Illinois or S. Wisconsin. I was planning on going back up there this coming weekend but I gotta get her to start. HELP!

Brian,

I feel you have a very low battery. I would really check your power supply. If your battery is dead, jump start it. Let us know how it turns out.

Jeff,
I thought about that and did the jumper cable thing to my trolling motor batteries and still it wouldnt turn over. I was getting plenty of juice, it just didnt get over the "hump" and go. Other ideas? Thanks Jeff.

You might try jumping it directly to the starter. This would let you know if the starters bad or not. Got oil???? Hopefully it's not locked up. Any how if it turns over by jumping it to the starter it could be the switch or a staring solenoid. There may be a fuse inline to the starter solenoid that is blown also. Check your manual for a location of the fuse and check it. Sounds like it's not getting juice to the starter....

Thanks Dutchman. I'll give it a look. Keep the suggestions coming everyone!

Perhaps it was a shock to your motor's system to get something better than Chain scuz for a change? :-)

[brian1785]

Steve,
You're probably right. Too much clean zebra mussel water shocked it into a coma! Hoping it's something simple.

I guess I must of missed this somewhere. Is it cranking over normally and not starting, or cranking slow, or not at all?
I have come to find out "not turning over" can mean different things to different people.
;)

[brian1785]

Sorry about the misconception. It is cranking normally and not turning over. Advice?

[perchjerker]

Ok, I would start with the basics.Look at the plugs. Are they wet? black?Then I would check to make sure you have a bright blue spark.

[Dutchman]

OK, as I understand it you motor spins over but won't run? Correct? Then I have to wonder if you accidentally bumped the kill switch. This will allow it to crank but not fire. Check it out.

Yea, he is confusing the term "turn over" with "start". I used to get it all time when I was a wrench.

[Pro-V]

Lets take it easy on him.I dont think that everyone is as smart as common internet junkies found on this post.Give him a break.I would take the motor to a quallified Mechanic and not use the backyard wrench approach.Good fishing my friend.

This is going to sound crazy, but 10 years in the business Ive seen everything.Make sure that you didnt bump the emergency kill switch.Youd be surprised how many weekends are ruined just by bumping that switch.

[perchjerker]

Hwy, Im not being hard on the guy...just clarifying what he was trying to say. We are trying to help him here.

[brian1785]

Hey guys, dont worry about me. I've got pretty thick skin. I didnt take any of your questions the wrong way. I DID check the kill switch at the launch. I also:
primed the bulb
checked the oil
checked the battery
jumper cabled the starting battery (just in case)
heated the lower unit
heated the fuel lines and water lines
prayed

Any other ideas? It is still under warranty so I guess I'll have to take it in. I was hoping to fish this weekend and not have to leave it for an entire week. Anyone know of a good Yamaha dealer? THanks again everyone.

a timing light (inductive pick-up...clip's on the plug wires...don't think you can buy any other kind any more) is the easiest way to find if you have spark on any "spark plug motor". hook it up to your battery (again clips on)pick a wire (if you just checking to see if you have spark) crank the motor over while pulling the trigger on the timing light and see if you have a steady constant flash.(the wires are long enough for you to sit at the helm and reach the engine).
if it's not consistant, you have coil,wire,voltage,or a plug problem. if it's good, you start to look for a fuel problem. same on a car/truck etc...great cheap tool.
hope that helps

[perchjerker]

Check for spark. Pull a plug, connect it to the wire, lay it so it touches a clean unpainted metal part of the motor and have someone crank it while you look for a spark. You need a bright blue spark, not a yellow one. A timing light will work, but it wont tell you if the spark is strong.
Did you look at the plugs?
Another thing to look at is your fuses.

[GrandPops]

How about the shift/throttle lever? On mine sometimes it looks like it is in the right position but is off just enought that it will not start. Turns over but will not start.
Worth a try.

I have not had any problems similar to yours and I have a 2001, but have you checked the water /fuel seperater? Is it full or empty? It is possible that maybe your fuel pick up in your fuel tank is froze up? I had a buddy this summer get a tank full of water right from a service station. Also there are some fuses on the front of the engine, I do not have my owners manuel handy to tell you what is what.
You said you primed the ball did you take the connection loose at the engine and give it a squeeze?

Good luck KLH

Isn't Ostrow in Fox Lake the local Yamaha dealer? Why not give them a shot at it? They'd probably appreciate the service work even if you didn't buy it from them.

[MarkG]

If lookin for N. Illinois dealer,Bob's Marine in Dekalb is a Yamaha dealer.

[brian1785]

I did check the plugs and fuses at the ramp. Bobs in Dekalb is booked for a week and a half. Im planning on going to LBDN this weekend so I wanted to get it done before then. Thanks for all the advice guys. I'll check those things. Ostrows is also booked tight. THanks again everyone.

Just to be throuogh and for anyone else looking in, to properly check the fuses requires more than just looking at them. The best way to check is with an ohm meter. You can also use a self-powered test light. A 12v test light will work if the circuit in question has power applied to it, you should get the light to come on when you touch either side of the fuse with the test light. If only 1 side lights, then the fuse is bad. If neither side of the fuse lights, then there is no power at that circuit. That may be normal depending on what circuit you are testing. Then there is always replacing the fuse with a known good one.

I have seen many a fuse bad that looks just fine, a lot of times it fails where you cannot see it. Glass fuses are known for this.

[brian1785]

Thanks Perchjerker, I didnt know that. Good tip!

[brian1785]

Just to let you know, it was the fuel pump that wasnt working correctly. Thanks to all for the great information.
