Phew

I went to the boat today to check out the white smoke issue we had last time out. 

I decided I want to change the coolant and change the oil because even if not needed, it's good practice for me.

I also wanted to take photos of all the systems so that I can confirm with our local Yanmar dealer that I have all the sores I need and get anything I don't have.

The coolant replacement was no easy. First I located the clear house coming from the fresh water system, and turned its butterfly valve. But nothing. Not a drop. I finally located another clear house so just had to try its valve. Only that valve was basically underneath the coolant reservoir and extremely inconvenient. Not able to un-tighten it by hand I had to also get a wrench in there which I finally managed with the tiny wrench I have. 

So I was able to get the coolant out. It was of course clean sonreally he whole thing was unnecessary but at least I know he process for removing and refilling it. 

I ran the diesel for 10 minutes after doing the coolant and great news! No white smoke/steam. So could have been that the key was not all the way on so I got an alarm, and the white steam that morning was due to humidity not a mechanical problem. Phew.

I also discovered that the manual bulge pump's diaphragm was cracked so I removed it and just ordered a service kit which will take several days to arrive. 

Tomorrow I'll do an oil change. Slightly more intimidating since the pump is electric and has to be connected to the battery. And the dipstick is very inconveniently located just like the nut for the coolant.
