Getting Code 25, Should I Replace My Knock Sensor?

  This is a relatively common question for Honda Aquatrax owners, due the fact that these jet skis are no longer in production and have aged 8-15 years.  The actual problem isn't always the knock sensor. It is very common in these older jet skis for the Honda ECM/PGM F1 to reach it's end of life expectancy. even though your Aquatrax may only have 100 hours or less.
