Isoflex IFV30-16S Engine Mount for Yanmar Marine Engines

Isoflex IFV30-16S is specifically designed to fit Yanmar YM, GM and JH Series marine engines.  

Isoflex self-aligning adjusters increase the mount's stud strength 3x by providing a compression fit. Our adjusters allow up to 4 degrees of bracket-to-bearer misalignment to reduce point loading.
