I need to remove my steering actuator and replace it as it is leaking pretty bad. I removed it years ago with the engine out so the bolts will come out easily, but don't remember the wrench size With the engine in it will be much easier to get the bottom one out with a self ratcheting wrench. Boat is not at my house currently so does anyone recall what the size is for those bolts so I can head to the store and buy the right size wrench.
