Subject: [worldcruising] More about diesel

Hi, I'm totally new to diesel engines, at least new to the responsibity to
making them run properly, and I have been reading with interest the ongoing
debate here to bleed or not to bleed.
I have a 33hp Kubota (I think they are branded "Universal" in the US) in my
Vancouver 27. I just completed a five-day single-handed maiden voyage in it,
sailing down from Phuket to Langkawi, Malaysia. I used the engine at least
some everyday. The third day out, the engine seemed not to want to sustain
high rpms, kicking in and out, cutting back from about two-thirds throttle
to one-third throttle, then back again. By the fourth day, one-third is the
best I could do. Otherwise, the engine started like a dream and ran
smoothly.
I had to leave the boat in Langkawi to race back to work and didn't get a
chance to poke around 'under the hood' (as if that would have solved
anything).
My question is, does this sound like an airlock problem? Given the symptoms,
what is the first thing I should try when I get back down there? I have a
lot to learn about diesel engines, but would like to do what I can on my own
before turning the problem over to a mechanic.
Comments, advice, flames, all gratefully accepted.
Jim
