oops, sent the last post before I was finished
Here is a Youtube showing the
noise level difference between the Epropulsion and Torqeedo. Small indicator of quality, but still....
I suspect the dramatic
noise level difference may be due to the hub of the Epropulsion being fluid filled, as it should be.
The Torqeedo is not fluid filled, but the more important difference IMO is not the effect on noise level, it is that once the Torqeedo hub heats up ( and they certainly do)
water gets sucked back past the
seals by the negative pressure as the space cools down. Then bad things happen, as many unhappy Torqeedo owners will attest.
