Hi Jim. Ya, that's the approach I have long considered. Much like the
steering mechanism I plan to work out. The side thrusters are heavy in the back
in relation to the pivot point so that if the pivot actuator failed, the
thruster would be pointing up. Give it some juice and up we go ! I had
planned an putting a spring on it to help it return to vertical. I was just
considering the electric motor as an actuator to eliminate an
additional thru-hull for the hydraulics. I could run the wires through the motor
lead hole. Biggest problem though is allowing the thruster to go vertical
if the actuator motor fails. I could also use an air cylinder rather than
hydraulics, but it would be either up or down. A "positioner" done with air
power is pretty complicated. I'll probably go with the hydraulics. Frank
