Kawasaki U-150 trouble vol 2

I found water leak from water pipe which fitting to cylinder. It has crack because water leak and then I try to remove that pipe but won't come off from motor..... shit happen!

Finally I decide lift and motor out from hull.

Water leak from this water pipe.

It had corrosion inside of bolt hole and stuck because this water pipe won't come off.

I used gas torch and heat and heat then tapped pipe. I just repeat and repeat then pipe came off slowly.

After removed gasket I find cylinder side damaged by corrosion. Oh my god!!
