Have any of you successfully recharged your marine A/C with an R22 kit? Mine is a 12K Mermaid and the instruction manual says nothing about recharging except to call a professional. There is a port just like on my cars but it is smaller. Here is one kit that I found with Google: http://coolantexpress.com/refrigera...echarge-kit/?gclid=CLTIlpjg37ECFVR7OgodAwYAAQ . Just like to have some confirmation that someone has brought their cooling back to life with one of these. Thanks.
