To figure out whether it’s the starter relay that’s causing the problem or the battery is by the number of clicks. The starter relay is what transmits power to the starter motor from the battery so it can turn on the engine. Just like cars and motorcycles, a starter is what starts your jet ski engine, and like anything else it can have issues. When your jet ski is not being used, use the solar panel to recharge the battery! Helpful Tip: To prevent the battery from dying on you all the time, get a solar panel. If you don’t have time, you need to at least recharge it for several hours. Let the battery recharge overnight if possible so that it will be fully charged. To give your battery a good charge, use a smart battery charger, one that won’t exceed 2 amps. If you turn the key and the display goes on, but when pressing the start button all you ger are clicking sounds, the battery is weak.If you turn the key and nothing happens, then it’s very likely the battery is totally shot and will have to be replaced.So, if your jet ski won’t start, before doing anything else immediately check the charge on your battery. This is why we tell everyone that a proper winterizing process is vital. Let’s get down to the nitty-gritty and talk about these issues in detail!Ī dead battery is the most common reason for a jet ski not starting.Įven if you have a new battery or you’re sure the battery is charged, a dead battery is the most common problem that occurs at the start of every summer season. But before anything else, check the battery! The problem could be with the fuel system or perhaps the carburetion, which can happen if you haven’t used your jet ski in a while. If the jet ski won’t start or run at all, the ignition is the first thing you’ll want to look at. When trying to troubleshoot a jet ski that isn’t starting, you can break the problem down into a few basic possibilities. It may mean more work, but if this happens it must be looked into immediately. The other problem that commonly occurs when starting the engine is that it won’t accelerate as it should.

This won’t damage the engine or other parts at all as long as you keep the RPM low!Īlso, never overlook the pre-ride checklist, as accumulated gas vapors in the engine compartment could result in an explosion. You can turn the engine on and let it run for 15 seconds without cooling. This is why it’s always a good idea to start your jet ski while it’s still on the trailer, or even better to try starting it at home in the garage. This can be especially frustrating if others are waiting behind you on the ramp. You’ve just launched it, but now your jet ski won’t start?
