AQAD41 B - Can anyone ID these Seawater plugs?

[colhel]

Ive just removed mine and it's identical to the heat exchanger plug in your first picture. But without the anode. I posted a link to Keyparts earlier in the thread. Its on there.

For reference its a 1/2 bspt

The drain plugs on the bottom of the turbo and bottom of heat exchanger are both 1/4 bspt.

You legend! It was staring me in the face all along.

Problem solved, plug in!

THANK YOU ALL!

Must correct myself. The 1/4 " is in fact npt (18 tpi). Which as 1/2 bsp and npt are both 14 tpi it stands to reason the block and heat exchanger are also npt.
