Yes, electric choke. Push in on key. It's working. It's an S115TLRX. As soon as I figure out which one of my 3 sons borrowed my compression tester, I'll do a compression test. Carbs recently rebuilt and plugs replaced (a couple of weeks ago. Ran great since then, but took a long time to...

Is it possible that with replacing all of the electrical/timing/ignition parts that you need to adjust your WOT timing advance? Does it run smoothly and strong all the way up to 4000 RPM's? If it runs fine up to that point, but doesn't go beyond that, does the cable continue to open...

Won't the gauges come with instructions? If you only ordered the actual gauge, you're pretty much screwed.

Diagnosis is pretty simple. A starter solenoid or relay allows you to use a small amount of voltage through your ignition switch by using low voltage, basically a coil of wire that when voltage is sent through it, it becomes a magnet and draws a plate toward it to make a connection. Use a volt...

The temperature sensor can be tested by putting it in a pot of water and heating it up. You'll need an ohm meter and a thermometer. Start the stove and hold the one lead of the meter to the end of the wire and the other to the body of the sensor. At some point the temperature of the water...

Not sure what prevents tilting when actually moving forward. I'd try putting in in gear and see if that prevents the motor from raising up too far. My '99 Yamaha 115 will tilt all the way up while in gear. Well maybe not all the way, but I know today when my son was driving the boat and got...

My 115 is almost impossible to start. Runs great once it starts, but that takes forever. Lately, the only way to get it to crank and stay running is to press the button to disengage the shifter and set the handle at 3/4 throttle. It starts and revs up incredibly high. I pump the bulb up...

Thanks guys! It is a 1989!, and as far as shifting goes, there are grooves and notches on the end of the tiller handle shaft for cables to connect to, but there are none there. Those can be ordered. The odd part is the side of the lower cowling has a groove cut out for the cables from a...

You mentioned timing marks on the control box. I don't know what you're describing. Timing marks are on the flywheel. Explain how you are checking the timing. If the timing is incorrect, this could very well be your problem and could cause serious problems is you have over-advanced timing...

If you find a part number on a part that you know what it is, I'd search for that part number on the internet and it might tell you what year model it is. Just a thought. I do that sometimes when I shop for the part on the yamaha website and then shop for it online to see if I can buy it...

If you're still using the Yamaha oil injection system, then it sounds like you are getting oil, but not gas. I had the same problem with my '99 115 Yamaha. If I could baby it enough to get it past idle speed, it ran great at wide open throttle. But keeping it running at idle and having to hit...

I recently purchased an older 9.9 electric start 2 stroke Mercury outboard. It was taken off a pontoon boat that was used in the lakes of Kentucky. It was used with remote start, steer, shift/throttle controls, but I want to put it on a small boat and use it as a standard tiller motor. It has...

I'v struggled with possible carb problems for several years. Finally, I broke down and bought new carbs. Still have the same problems. Choke it and lift the fast idle and it fires up and revs high. Try to throttle down and it shuts off. I've tried everything. I recently had to replace a...
