I've tried to improvise both kinds of covers with cushions as well as cardboard, similar to some of the sunbrella cockpit blockers on the market. A Fiberglas barrier's effect would be much higher vibration reduction, than nothing at all.
No sure about the M but I can fit a 22" wide, 17" deep, 17" high plastic bin from the $ store that almost encloses the engine well and fits under the capt. seat. Excellent bin to hold fenders and dock lines and also deadens the sound. A heavy duty bungee keeps the bin from sliding into the engine and away from the electrical, gas line and steering linkage.
