Hello Tony,how are you?

Please see photo attached of old engine,new setup is the same,with new original Yanmar engine mounts,old one skipper throw away,that’s why i don’t know previous setup or height of engine itself.

Thank you.

Since you are talking CV joints / aqua-drive, I think good very good pictures would be a pre-requisite before any good help would come. Close couple vs. a long shaft requires totally different “tools”..

Carden shafts are not as forgiving as CV joints, so if you followed this diagram, you’d be totally good.
