Did you solve your seawater pump problem, and if so, what did you find out?
My engine is running, sounds great, shows no sign of problems except blue smoke, which I suspect is because the engine was rebuilt, but never used in 10 years. Obviously burning oil
, probably rings were never seated in, and possibly "iron worms" in the cylinders from sitting unused. I started a thread on oil
burning in a rebuilt engine on the forum that provided a lot of good break-in tips.
Now, I have decided to stay in Oregon
for the winter to continue completing my refit
, which also means taking time to learn my engine even though it appears to run great. One thing I found was that quite a few details on my engine differ from what the workshop manual shows for an MD21A. The seawater pump is one of those things. I have the big, boxy heat exchanger
, but the seawater pump appears more like the description for an MD21B?
At the moment, I am trying to figure out if mine is an A or a B. Having no experience with this exact engine, what I know is only what I was told when I bought the boat and from a professional diesel mechanic
I had look it before I bought it. Since then, I have found some pretty sloppy work from that mechanic, so can not rely on his opinion.
Any of you know how much is interchangeable between the 21A and 21B?
What should I look for to find out exactly what I have and how much is a modification?
