Hi there

I have a 1996 Yamaha 50HP four stroke and there is a vacuum hose that attaches to the bottom of the airbox, but I'm not sure what it is for. I can't see it in the service manual and I can see any place where the other end should attach. Can anyone shed any light on where this should go?

Just in case anyone else is wondering, I found out the answer to this question. It turns out that it isn't a vacuum hose at all, it is a drain hose to get fuel out of the silencer should the carburettors flood.
