Isoflex IFV55-12S Engine Mount for Diecon and Other Marine Engines
Isoflex self-aligning adjusters increase the mount's stud strength up to 3x by providing a compression fit. Adjusters allow up to 4 degrees of bracket-to-bearer misalignment to reduce point loading.
- Stud size 1/2" (M12)
- 4" mounting center (102mm)
- Minimum free height 2.36" (60mm)
- Replaces factory mounts for Beta Marine, Diecon, Fiat-Iveco, Lombardini
- Provides at least 85% vibration isolation at worst case engine idle (4cyl and above) = less equipment fatigue, maintenance and associated noise
- Encapsulated core allows for fine tuning of inverted stiffness
- Resilient element co-polymer resists fuel, oils, water and hydraulic fluids
- Hold-down bolt slots can be rotated to any direction for easier installation
- Fail safe
