port

Got my 787 rotax installed back into the craft and have begun the reassembly process. I noticed this port diagonal from the center of the rotary valve, does anybody know what it is for? I have searched the owners manual over throughly and can’t find any mention of it, however I doubt any OEM...

I lost my port side arm rest going out onto cayuga lake in new york. I've looked all over the internet and nobody sells the part anymore. Was wondering if anybody was selling one here or knew anyone that was selling one. The 2009 also fits, the part number is 204614432. Thank you in advance! -R.H
