Yamaha FX battery breather hose

Hi Guys,

Was washing down my ski yesterday and as I was peering into the back compartment when I noticed the instructions on the battery breather hose. 'Battery may explode if breather hose not connected' + diagram

I'd always wondered what the spare hose with clip was lying in the bottom and I think I've seen someone else ask the question on the forum.

The ski's even been in for a service and no one picked it up!! Clips onto the back of the battery.

my ski has had the battery replaced and used a sealed battery and that vent doesnt have anywhere to attach to now lol

99% of skis that come in for me to service dont have the breathers connected to the battery,they either fall off because they ar'nt put on when the battery is replaced or the rubber hose has perrished and will not stay put dont be to alarmed!!!
