I installed one of the Raritan conversions in my first boat...

Which one?

It does work well but is quite noisy.

All electric toilets that flush using raw (lake, sea, river) water are
noisy...'cuz contrary to popular belief, it's not the macerator or
discharge pump that makes all the noise (or consumes the most power),
it's the intake pump. A toilet designed to use onboard pressurized fresh
water is so quiet that it's actually quieter than many household
toilets...and also consumes less power--10 amp draw vs. 16-35...and also
uses anywhere from 30-50% less flush water.

However, if swapping a raw water toilet out for one designed to use
pressurized water is more than your budget will stand, mounting the
toilet on at least 1/2" of foam rubber will quiet it down a lot.
