That's exactly the same place where mine snapped on the starboard side, so it has definitely got to be an issue with the 60 Etecs.
Mine is a 2011 model and it happened in choppy run between Mull and Iona in 2012 I think..... while on holiday with a group of friends off here . Maximus towed me all the way from Fingles cave to the sanctuary of Easdale Island off Seal.
Dam fine chap he is too..."something I won't forget Maxi BTW".
Mine was renewed under warranty by my dealer Liverpool Power Boats and Ian the proprietor had quite a fight on his hands with Evinrude at the time. Anyway all has been okay for now fingers crossed.
Also my engine was raised up a hole at the time leaving a gap which could have been a factor to the saddle breaking. My dealer fitted a spacer to replace the gap.
I hope all get sorted out for you mate 👍
p.s. it also happened to Two Stroke Mick on here too......I would definitely not pay the 1600 quid and fight your corner. If you need any help with this send me a p.m. also I'm sure that TSM will help too
