AIR IS SUPPLIED BETWEEN 2 AND 3 SEAL ,WHY IT IS NOT SUPPLIED FROM 1AND 2 ?
good but you should develop your language
why does liner rotate with the propellor shaft?
Which liner..??
Liner rotates together with shaft liner is fixed at the shaft and has o-ring so they rotate together and liner does not leak anything.
How many lip seals are there in fwd and aft
4 in aft and 2 in fwd

@@Mk-sn3mb right 2 for sw and 1 for L.O but in this it's shown 3 or 4
Always 2 for fwd and 3 or 4 to the aft side.
Everything is nice about you but I suggest you to work on your way of explainability as you fumble and get stuck number of times,while reading out the slide. Moreover,it's good to see if your lecture is bit more interactive rather than reading slide line by lines, making the video stretchable. Just a cue. Anyway you doing good job. Keep it up
bad narration....
