Hello, I have a seadoo Challenger 1800 2002 with mercury 210, 2 stoke. This year, I have somme difficulty to start the boat. It's like it has some difficulty to spark. (full battery and new sparkplug) But, when i'm playing with the safety button (kill switch) (on/off with my thumb) I finally start the boat after several tries!! Of course I have to leave my thumb on the button and put the kill switch back when the engine start. I have read on the forum that someone with the same problem, replace the crank sensor. Do you have an idea of the part number and what it look like ? I don't find anything on the parts catalogue. Thank you!!

Unplug the kill switch behind the dash.

What’s it do when it’s unplugged?

What I’m saying is unplug and leave unplugged and crank the boat. When kill switch is pushed in it breaks a circuit. It’s a normally closed switch so unplugging it does the same thing as pushing the button.
