Mine is a 2002 , charging option was dealer installed factory supplied , I just checked the website and it is there 5a lighting/charging option .Its between weight and RPM range , not in the bullets .

I've run with the hatch down , but mostly keep it clipped to the backstay for quicker access . When underway , I keep the hatch above the tiller off and stowed below , also my motor well is rarely submerged .
I never see or smell the exhaust when under way.
