dubo washers for props

[okey0]

getting ready to re-install the prop shaft housings to the hull. Is there anything special i should keep in mind when it comes to the dubo washers? What are the torque values for the bolts? i dont see that info in my manual.

2 person job.. Back then they did not have silicone,, the miracle sealer! 8mm bolt tighten with 3/8 ratchet hand tight, you gotta learn the feel/
