Designed specifically for marine applications, the Double Acting Shear Mount is unique in incorporating 2 rubber elements which are pre-loaded against each other.
This provides excellent isolation, along with good control on problem installations.

The rubber component is covered by an oil shield to protect it from petroleum based products.
These mounts are preloaded 0.19", based on the anticipated combined engine and transmission weight, to limit engine movement.
To facilitate in the ease of installation the mounts are height adjusting.
These particular mounts are unusual in having both longitudinal and dual transverse elongated mounting holes for difficult alignment situations.
