Selection of Proper Engine Mount

Please provide these details to Pacific Marine and Industrial
(if you are replacing mounts, skip below steps and provide dimensions of existing mounts and total weight of engine and gearbox)

1. Manufacturer and model of engine and number of cylinders
2. Type of gearbox and reduction ratio.
3. Weight of engine and gear box combined (from manufacturers literature)
4. Is the flywheel in the conventional place between the engine and gearbox?
5. Position of engine mounting points.
6. Find the center of gravity by balancing on a roller (if possible). If not possible, assume 60% of
weight on rear mounts and 40% of weight on front mounts.



Installation of Engine Mount:
1. Maximum clearance between bottom nut and oil shield is 10 mm or .375 inches. (applies for all models of engine mount)
2. If more height is needed, use spacer under the mounting base.
3. When engine is in place and at rest (but before mounts are tightened down), engine mount studs
must be centered in their holes (no preloading in any direction).
