The main steering chain and wheel has a good gear ratio for ease of use in worst case seas.
The ET does not!!
Your ET must have that main chain broken or released to use the ET.
Install your ET with the chain connected and you will find out!
The ET will be a major arm fatigue since the force applied is a simple lever arm ratio. That is limited by the clearance horizontal arm swing. Note the welded on port/starboard rings on my post #17 above.
I bought 2 cheap "come alongs" to hook to my stern cleats and those rings. I will use the "come along"
to move the ET and hold it in position.
It will take an amazing amount of arm strength to steer and hold in even moderate seas.
I expect to have my hands full, if I am using the gusher pump and maintaining boat safety in high seas.
Tip: Don't wait till an emergency to find out. I do an annual "safety drill" with the Admiral to assure we remember what actions are needed.
Safe boating...
