Unfortunately, despite its large motor mounts, hush box and muffler,

located inside an engine room, other than from a fair distance off,
outside
the boat, it's enough to drive you (well, me, for sure!) mad with
the noise,
and, to a much lesser extent, the vibration.

You need to install soft mounts, say about 40-50 durometer, that will
go into resonance well below the operating frequency of the unit
which is probably 60 Hz, based on 3,600 RPM operation.

Get the weight of the unit, then talk to AquaDrive in
NJ.

Soft mounts are a basic part of a successful A/D installation.
