Engine run up today

Treating this entry rather like a log book today.

Started engine at 0950 local time here in Southport, NC. I did this after diagramming the fuel tanks, the fuel return lines and marking the tanks again (the old markings are fading). I also cleaned the tank tops of dirt and dust, cleaned the floor panels before replacing them, along with all the interior of the mounting for the panels.

I double checked oil levels today, they are normal.

I made sure the return line is opened to the #1, Aft tank, as that’s where I’m pulling diesel from.

Transmission levels fine.

Coolant fine.

Engine started hard (it’s very cold today, was in the mid 30s this morning. It’s 46 now.

Engine did start though, without any problems, other than taking three cranks.

Checked raw water flow. Good.

I brought engine up to running temperature, 160* F and that took 24 minutes.

Pressure was high (almost 80 psi) at start, but as temp increased the oil pressure dropped to normal.

Brought engine up to 1200 rpm for 10 minutes.

Put at idle speed (about 980) and put in forward gear.

Brought engine up to 1100 rpm in gear at dock.

Pulling against docks now strongly, remained engaged.

Has been running 25 minutes in gear with no issues. (1035)

Oil pressure: 40

Engine Temp: 160

Charge: 14.5

Engine running smoothly at this time. Listening for timing or engine speed changes. Seems steady. (1040)

(Listening to Margaritaville Radio, because I’m sick of the cold)

Ok… 1055, engine shutdown.

Temp, oil pressure, voltages all the same as above. Engine didn’t vary it’s tone or speed from 1100 rpm. All systems “nominal”.

Going to wait a bit to let oil settle, and take a reading. Then will read it cold later today again.

Edit: Checked it as it is cooling, and oil level seems higher than it was. Will let it get totally cool before testing again. Also did an oil blotter test; this is where you place a drop of the oil from the dip stick onto a piece of paper and let it absorb into the paper.

In chemistry, this is called Chromatography. They have gas chromatographs, but I don’t have one of those. I’ve got paper. So I did a cold and warm drop test on the paper and marked it. I will do one more drop test when the oil is cool again. So FAR, it shows it pretty clear of any contaminates other than soot.
