Hello Everyone,
I just joined the forum after reading through a few threads and found there are a lot of knowledgeable people that might be so kind to help me with this old outboard.
Today I started up the outboard with the earmuffs on and found that the bottom cylinder is blowing out a spray of water while running. I found the below post which I think sounds very similar to my problem.
The questions I have are

Head Gasket

Exhaust

29 - 317215 - PLATE,Exhaust manifold
30 - 317228 - GASKET,Exhaust manifold
86 - 319097 - GASKET,Exhaust manifold
Background
The outboard has been well cared for before I purchased it and I have had it running on the water but admittly it was running bad with a big deadzone in the middle of the throttle range. If i managed to jump the deadzone it would get out of the hole for awhile but then bog down to just above idle speed. I think I might have been running on two pistons and found that the coil connection on the middle piston was not working (no spark) did the troubleshooting steps and confirmed. I have ordered a new power pack and will be working out how to install it but thats another thread...

The questions I have are
- What is typically the more likely cause for water leakage, from my understanding on the below "Reference forum" there are two different areas the water is likely to be coming from. Head Gasket and Exhaust Gasket/Plates etc area.
- Does the volume of water give any clue as two which might be the cause of water leaking in ? Reason I ask is because I am in Australia and I can get my hands on the "313413 - GASKET,Cylinder head" but buying the Exhaust parts is going to be harder and take mucher longer to get hold of.
- What's the best way to confirm where the water is coming from ?
