OK all these entries are now pretty dated, but we are testing a Sillette Sonic with an
electric propulsion motor in our lab at
Electric Yacht. While it's not
cheap, the Sonic unit with no lower unit shifting gears is ideal for the
electric motor, since that reverses the whole drive train.
The Sonic does mount hard to the
hull as opposed to a
gasket and a hard mount to the engine/transmission.
Incidently... I see that I can register as a "commercial vendor" and will try to change my settings to reflect that. I am connected with Electric Yacht as its Director of
Marketing. So few sailboat owners have electric
power on their radars that I feel the need to be more of an evangelist than a promoter.
