SOURCE: Waverunner will not start

Check the fuses under the front in a round cover, 1 fuse is for the starter,but the cover must be on after checking the fuses.

SOURCE: waverunner sat for 4 months. thought battery was

Try jumping the waverunner using a set of jumper cables and your vehicle, this will rule out if the battery is bad. If you still have the same issue, check the connections. The connection at the starter or another place may have corroded a bit. Yet another option is to remove your spark plugs to make sure that your motor has not hydraulically locked. Once you have removed the plugs try and turn over the engine. You may need to ground out your plug wires if you have an electronic ignition to protect it. I hope this helps.

You need a new starter relay. It is located in the black box on the rear wall of the forward compartment. It is the one with the 2 red starter cables going to it and a brown and black wire coming off of it.

hate to break it to you. carbs need to be rebuilt. the new fuel doesnt bode well for the carbs, clogs a really small filter and jets in the carbs
just had it done for the second time for a cost of $550/each time
