Good video. Thank you Changing spark plugs every season is not mandatory. Most owners do not use their PWC for enough hours during a season to have to change the spark plugs . Refer to Yamaha’s maintenance manual for spark plugs replacement interval on your waverunner model and model year.
Fogging oil can foul plugs out. So changing them every season is a good practice. And her svho is clearly modded. So fresh spark plugs every season is a cheap way to keep it running tip top. Good video. Only thing different I do is after fogging. I reinstall my old plugs. At the beginning of the season. I run it on the hose to burn off the fogging oil. Then put my fresh plugs in
