I was doing what I always do and they lasted for one day and when they failed they all failed at once and caused catastrophic damage. No I would I take OEM mounts with you and/or preemptively change your mounts every year if you ride waves. Don't take my word for it ask around.What kind of stuff were you doing in what kind of hull and how long did they last? I think the Yamasaki conversion mounts in my 550 hull are a different dimension than oem Superjet mounts which is what I’ve always run in the surf. I’m just wondering if I should preemptively order a backup set from Rhaas for surf trips.
