I've been running jets for years behind offshore boards, no problems, even with a 2 or 3 oz weight infront of a 40 jet to get added depth. I have my own set up for releases on the jets. Along with quite a few articles I have written and posted on this site, they have not gotten all of the articles posted, not sure why...maybe because I'm no longer a member, but hey I was a member for a very long time and they requested articles......anyways, hope this helps
