A jet ski not starting is most often a dead or weak battery. A bad starter relay can also be another reason for a jet ski not starting. Usually, when you hear multiple clicks from your jet ski, it`s a bad battery and if it`s one click it`s a bad starter relay.
There could be several reasons why a WaveRunner is not starting. The simplest and most common fault is when the shut-off clip is not properly attached or the tank is empty. Other common reasons could be electrical issues like malfunctions with the battery, spark plugs, fuses, or wires.
Spark plugs are often the problem if your jet ski engine turns over, but doesn`t start, especially if you have a 2-stroke jet ski. Take the spark plugs out and examine them to see whether they`re wet or dry. If they`re dry and light brown in color, you have the correct fueling.
The fuses on a jet ski are located in a plastic box, known as a fuse box or electrical box. This sealed grey or black plastic box is mounted inside the engine compartment usually near the battery or hidden somewhere under the top deck.
A loose battery connection can cause a jet ski to stutter, shut off, or even bog down. A jet ski needs a battery connected at all times to run, or it will shut off or act funny. Double-check the connection to the battery and if the battery is over 3 to 5 years old, then it`s a good time to replace it.
Most manufacturers produce machines designed to last around 10 years; at 30 hours a year, the approximate average lifespan of a PWC would be around 300 hours.
If your engine in your jet ski doesn`t crank at all, but you can hear a rapid clicking sound, it means the battery is weak. Don`t confuse it with a bad starter relay! (It gives only one click if it goes bad.)
The best way to jump start a jet ski battery is with another battery that is not connected to anything else. It`s also ideal to use a battery of similar size, don`t try jump-starting your jet ski battery with a tractor battery! Basically, you should only jump start a jet ski from a jump-starter pack.
Although it`s possible to jump start a jet ski with a car, it`s highly recommended you don`t do this! This is because there`s a huge risk of damaging the jet ski`s electronics, as a car`s charging systems and batteries are more powerful. What`s more, a jump start can even damage your car!
In the event you have a completely dead battery do NOT attempt to jump-start the battery with your car battery or even a jump pack. This can cause extensive damage to your jet ski`s electrical system and is not recommended.
Check the fuses of the ECM, and electric starter, as well as the main fuse. If your Sea-Doo still won`t start, you may want to check and clean the battery. If you don`t use your Sea-Doo very frequently, over time its battery is discharging itself, which means it probably just needs a charge.

I have a Kohler Condidant 5 Generator that will run as long as you hold the start button in. It dies when you let off. I have a harness for the remote switch but no switch – It also will start the generator when you cross the red and black wire and run as long as you hold them together. There are 3 wires to the main switch and 5 to the remote switch. Does the starter stay engaged the whole time you hold the start switch or does the computer release the starter once it is running? The Generator is producing electricity because I tested it while holding the start button. Some where is a wire that shold tell it to keep running. I have read online many descriptions of the same problem, most are told the board is bad so they replace it and still have the problem. Have not found a solution. Talked to a marine machanic today and he said he fixed his friends generator doing the same thing by running a bypass wire but he couldnt remember exactly what he did it was a long time ago. Can anyone help me. Thank you
ANSWER : The problem is either the ballast resistor or the starter bypass relay. The bypass relay should be part of the starter solenoid. I’m afraid I can’t tell you exactly where the ballast resistor is located. It should be a physically fairly large resistor made of ceramic. It should be retangular roughly 1.5″-3″ long and 3/8″-1/2″ accross with a wire on each end. It could also be a coil of wire mounted on a phenolic board.

Yamaha waverunner I acquired a yamaha waverunner that has been sitting for 8 years. i finally got it to start and after letting it run dry for about 20-30 seconds…oil and water began running out of the rear below the propulsion outlet and under the rear deck..the motor compartment is free of any oil or damage and the engine still starts. Any idea on the damage or what should I do at this point?
ANSWER : Check for corrosion of the engine as leaving it for long any water left in the system will cause problems.

My 1988 honda fourtrax 300 keeps shutting off after about 30 minutes of riding. It bogs down then it shuts off it doesn’t just shut right off. I will then have to wait about 5 minutes to start it up again. It seems like when it gets hot it does that. What could it be?
ANSWER : It’s possible that you are getting a vacuum in your gas tank because the cap isn’t vented. This can cause this exact condition.

I have a New Balance 1400 (a few years old). When I run (7.0 or higher) the treadmill shut off. I loosen the belt than I retighten it. I ran 5.5 miles (ranging from 7.0 to 7.4). It ran great. Today it shut off before I got to 1 mile, Than I got it running again and it shut off after only .5 miles.
ANSWER : I wish I was there to get a look at it I don’t think its a electronic problem sounds to me from the description the motor may be getting hot. my suggestion would be to unplug it and take a can of air to the motor and blow it out get the dust and dirt off and out of it if possible most motors are sealed others are very accessible. also do the electronics this couldn’t hurt. a can of air is cheap and it could make a big difference as far as keeping it cool then plug it back in go for a run if this works great if not you may have a bigger problem with the motor. after a few years the bearings tend to dry out and the motor may be starting to fail if that is the case I would look to Ebay you can usually find one there for about 50-80 bucks I hope this has been of some help

I have a 2001 Yamaha XL700Z Waverunner. The compression on both cylinders is about 120, it starts and runs fine – dry. Won’t quite idle, but I can start it and rev it up fine (for a short period, of course). However, as soon as it gets in the water, it will barely run – it will start and sputter and you cannot get it to run more than a few seconds or rev up. Take it back out, let it dry, starts & revs fine. It is not getting any water in the casing that I can tell, its almost as if water is getting something wet through the cooling system that I cannot see?
ANSWER : Try cleaning the carbs and the fuel lines, filter
