 Rick,
you might have thought through this, but looking at the video again, I don't know what overload protection the linear actuator has & as the actuator would need to fully close the valve it's motor would be stalled at that point. 
Normally the actuator has a switch that stops it at the end of it's stroke but timing the actuator end stroke with the full closure of the valve would be difficult. 
Same for opening but there is a bit more leeway as the valve doesn't have to be fully opened.
I think you said you were using a toggle switch. I would use a "spring to centre" toggle
switch so you can't accidentally leave it on & stall & burn the motor out.
Also maybe add a couple of micro switches that activate lights on a panel to show
valve position seeing as the valve will be hidden under the floor boards. 
I have seen small clear boat access hatches that could give you a visual check on
valve position & easy access if you needed to take the actuator off & manually
operate the valve.
Cheers Alan
