My dad recently purchased a used sailboat. It had a (I'm guessing here) around 16HP, 2 cylinder diesel engine in it. To make a long story short, he ended up pulling that engine and is getting a brand new Vetus (a marinized Mitsubishi diesel) installed.
Hes gonna bring the old engine to me and I'm gonna tinker with it. I was hoping that some of ya'll could give me some advice on what may be wrong with the engine and where to start troubleshooting. If nothing else it would be cool to tear it down and see whats wrong.
Here are the symptoms:
Brand new 1000CCA battery, fully charged. Hook it up and start turning it over. Its turning over very slowly. Acting like its a dead battery.
220 amp jump starter later, its turning over a bit faster. It has an intake heater, its working. Tried starting fluid as well. It acted like it wanted to fire a couple times but just wouldn't.
Looked at the oil and its a milky color on the dipstick. Probably not a good sign.
After having a mechanic come and look at the engine, they finally found the compression release. After tinkering with the engine for a while, they just figured it was best to replace it, so out it came yesterday.
So it won't start, has milky oil, cranks slow even with a good battery and brand new starter. Since it is a boat engine, it has a hand crank for starting it in an emergency if the battery is dead/starter is shot, etc. It was VERY hard to turn over by hand... it seemed like the compression was still good.
Also, the water pump isn't working - not sure if there is a clog in the system somewhere, or what. Its raw water cooled, no heat exchanger.
Anyway, if I get it running, I want to hook it up to something like this:
- Harbor Freight Tools - Quality Tools at the Lowest Prices
Anyway, he should be dropping it off here this weekend, so I'll post up some pictures and my progress with getting it running again. If I get it going I'll need to find a small radiator, an electric fan and some tubing to plumb it up - any ideas where to find one? For now I'll see if i can get the water pump to suck water from a tub or a bucket.
