Motor Mounts or Not?

I had a Proline system for 15 years. The motor was mounted to its base (which was of a piece with the sand filter base) quite neatly and I never had a problem. But because of age and parts availability, I switched this year to Hayward. When the men came to install the Hayward there was no mounting base for the motor. The just placed the motor on the concrete slab and told me that this model motor "doesn't come with a base." That can't be, can it??? Won't it just flap in the breeze sitting there unmounted? Even the owner's manual says "mount the motor to the base. . ." Tell me I'm not crazy.

I've been running my Hayward pump for years just sitting on a concrete paver. It doesn't move around, doesn't rattle and is just fine.

Well, the company did, after all, supply a plastic base for the motor, so it didn't become an issue about the motor mounts. Any tips for decreasing the noise of the filter. Not horrible, but maybe carpet under the base?

Mine's like Carl's, has rubber feet - never moves, never shakes, it's actually nice to have it "floating" since it's easy to take indoors for winter and I don't put stresses on fittings or pump housing when messing with the plumbing.
