Yamaha MR-1 High Output-MAJOR PROBLEM! WATER IN OIL!

Read more for further details.
Found water in my oil. Damn. I began with a couple of easy fixes, to no avail. Still had water in the oil, just as bad as ever. Then suspected worst case scenario....the head or head gasket. So I tore into the engine to investigate. Turns out it was something else that wasn't nearly as complicated as taking half the engine apart. In hindsight...there was never a need to remove the cylinder head. You'll see why in this video.
But the bottom line is, I eliminated all possibilities and now THE PROBLEM IS SOLVED!
I hope this video will help anyone else with a similar issue. INSPECT THE HEADERS FIRST! Especially if you operate in salt water. If these surfaces have corrosion breaching, water will enter the cylinder head due to valve overlap and aggressive cam lift, and being in such close proximity to the head.
FYI: The first and ONLY point where cooling water should meet exhaust gases is at the end of the left side exhaust pipe where the rubber coupler connects it to the waterbox/muffler. Anywhere before that can lead to water being sucked back into the engine.
FINAL NOTE: If you ever have to remove the cylinder head, remove spark plugs, then valve cover to expose camshafts and timing chain.
Drop a long wooden dowel in front cylinder.
Rotate engine coupler CCW until no further upward movement of dowel is detected. This will bring it to TDC.
Make sure the front cam lobes on intake and exhaust cams are facing away from the engine. If not, continue to rotate coupler another turn or two until at TDC with cams oriented correctly. Pay attention to the dimple on the camshafts and be sure they line up with the index arrows on the camshaft caps.
Remove caps (refer to a manual for correct torque and un-torquing sequence) and keep the caps oriented correctly with the cams, do not mix them up. Then remove timing chain tensioner and this will loosen the chain, at this point, remove the camshafts.
At this point you can remove the head bolts and then the cylinder head.
Reassembly is the opposite order, BUT PAY PARTICULAR ATTENTION TO YOUR TIMING MARKS ON THE CAMSHAFTS AND CAPS, and make sure you are still at TDC.
