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.

  • Stud size 5/8" (M16)
  • 6.85" mounting center (174mm)
  • Minimum free height 3.82" (97mm)
  • Replaces factory mounts for Yanmar marine engines in the 15 hp to 125 hp range
  • Provides at least 85% vibration isolation at worst case engine idle (4cyl and above) = less equipment fatigue, maintenance and associated noise
  • Corrosion proof, electrically inert, engineering grade polymers resist oil, water and hydraulic fluids
  • Metal components: marine alloy, stainless steel and components zinc plated to ASTM B633 Type II SC3
  • Fail safe
  • Easy to install
