3 Ways to Troubleshoot a Jet Ski Engine that won’t Start

by | Oct 16, 2018 | Interviews

Last time we talked to Todd, he let us know what we should do to get a jet ski engine to start once it’s been soaked in a capsize. The RaftUp team got several responses asking for his advice on what to do when a jet ski hasn’t capsized, but it just won’t start. We reached back out to Todd for his advice, and he offered these 3 jet ski troubleshooting tips:

Tip 1: Check the Spark Plugs

Spark plugs are often to blame if your jet ski engine will turn over but just won’t start, especially with two stroke jet skis. The mixing of gas and oil with a two stroke engine does a number on spark plugs. Of course, it’s always a good rule of thumb to keep an extra set of spark plugs handy. When you’re replacing the spark plugs, Todd recommends putting some starter fluid or a tiny bit of gas into the spark plug holes to give it a little boost.

Tip 2: Make Sure the Fuel is Good

Depending on how long it’s been since you’ve used the jet ski, a very common problem can be fuel quality. Fuel now has so much ethanol these days, so it’s a good idea to put some ethanol stabilizer in your jet ski every time you fill up. An ounce of prevention goes a long way in protecting your investment and your fun day on the water. 

Tip 3: Do the Electric Slide

Sometimes you’ll press the jet ski’s start button and it won’t even pretend to start. If you’re getting the silent treatment, you probably have a problem with your battery or starter solenoid. The battery is an obvious fix, but not as many people would think to replace the starter solenoid. It’s a simple and very inexpensive repair that should take at most 30 minutes. Todd recommend finding this part on Amazon, where you can find the piece for less than 20 dollars.
