Milky/Foamy oil in a 2008 AR210 with 825 hours

[WREKS]

@danzr1 I have not found the water tube emerging from head to be a problem. My milky oil problem was a small corrosion canal that had developed in the head on the exhaust side by Cylinder #1. It is documented in Milky oil repair.

Update: Engine swapped and I'm back on the water!

I bought an 06 vx110 deluxe last Wednesday, pulled both engines and put the vx110 engine in the boat on Thursday, and was on the water Friday after aligning the engine and hooking everything up. Here is a brief breakdown:
Thursday:
Removed AR210 engine (about 3 hours). Using a sturdy tree branch, a come-a-long, and 3 ratcheting tie-downs, I pulled the engine with a friends help. The tie-downs allowed me to articulate the engine to get it out of the small opening. The front of the engine had to be tilted up quite a bit. I kept everything that I possibly could intact. I had to cut of the fuel line crimps and pull the fuel line from the intake and cut the fuel pump wire so I didn't have to remove the floor over the fuel tank. I also noted the shims for the engine mounts. Next I pulled the waverunner engine out (1-2 hours).
With both engines out, I checked for differences and realized I had to swap the wiring harnesses (Had to put the ar210 harness on the vx110 motor). It's a lot of connections, but easy to do. Once that was completed, we put the vx110 engine in the boat and the bad engine in my truck for a future rebuild.
Friday:
Aligned the engine and tightened it down (12 ft/lbs is the spec, but it felt like it wasn't enough. I'll re-torque in a few weeks). Connected electrical, exhaust, and cooling lines. Attached the fuel line using 2 ss pipe clamps, replacing the factory crimp fittings that I had to cut. Soldered the cut fuel pump wire and used heat shrink tubing on the joint. At this point I tried to start it and she fired right up first try!

Here's a few notes:

• I was able to keep the exhaust all the way up the the last rubber coupler (before the waterbox), so no gaskets to replace
• Both engines were shimmed from the factory, but were shimmed the exact same way (respectfully). There was nothing for me to do other than place the 4 identical shims back and everything looked good. All the shims did was raise the engine up equally.
• I kept the ecm with the engine, but quickly realized in the water that the 06 waverunner doesn't have no-wake mode. Keep the ecm with the boat, not the engine
• Having the engine hatch cover off is a great time to re-insulate it if it needs it

Overall, the job was relatively easy because of all the great info on the forum, the step by step guide from @itsdgm, a friend to help, and of course the right tools.
Thanks everyone!

@cdave2000 I need to have the same swap done except the donor VX deluxe is a 2010. When you say swap wiring harness is that basically all of the wires that normally stay on the engine when you pull it? Also sounds like you kept the wave runner ecm with the engine which I am inclined to do although that means I won't have no-wake mode - did that 06 waverunner have an computerized security feature and, if it did were there any problems related to that? The 2010 vx deluxe has a security thing with a keyfob, there is a low speed mode worked into that also so I am concerned about how integrated that might be with the ecm and what would happen without the security components being on the boat. Maybe I should just keep the ecm from the boat assuming no big challenges with that - I guess the only downside would be wrong hours for the engine. Any thoughts appreciated, Thanks!
