I am out of the office today, send an e-mail to
MJthomas@bennetttrimtabs.com include your address and the parts you need and he will be delighted to send them to you, no charge.
The actuators will be fully retracted when you mark the transom. They are full retracted by default when they are not hooked up to the system, there is a spring inside that pushes the piston fully up when there is no hydraulic pressure in the system. The bump can usually be mounted aft in one of the compartments near the transom on that boat.
I hope this helps,
Tom
