Reinstalled the Swim platform. Still have the central strut to add but it is great to have had the help to get this beast up into place.

 

Pulled the heat exchanger core out today to inspect. Looks good. I will give it a cleaning and then reinstall.

 

Installed the Zink for the prop shaft. I should get 3 months out of this, then I will dive and add another.
Found a nice little oil extraction pump direct from China. I hooked it up to the oil extraction port. This would ll make oil changes so much easier.
Pulled the main battery. Stressed tested, topped up with water and tightened connection points.
Here is the front of the engine where the heat exchanger goes. We have a bunch of stuff to put back together now.
