I work with military aircraft that are newly delivered from
Long Beach, there is a team of mechanics to meet it and fix all the
write ups from the trip up the coast. The issue is not that there is a
quality problem, but that the things are built a little different every
time and there is not the huge production volume to work things out.
Toyota and Honda introduce all their new technology in Japan for a few
years before fixing it and then exporting it to the US. I think this
gives a false perception that complex machines can be produces and work
flawlessly.
If you own a complex boat, you need to either have the money to
continue to have it fixed, or learn to enjoy working on it as much as
you do going out on it. I suspect Cal 20 and row boaters have a much
higher percentage of their time on the water vs doing repairs then the
rest of us.
I put a new Yanmar in my 38' sailboat. It through a rod at 400
hours while in Mexico. Fortunately they covered the cost. I don't blame
it on quality, just chalk it up to the fact that it's a boat.
I do try to go anywhere then West Marine. They seem to be the
K-mart of chandleries and go out of their way to have poor quality
materials at a high price.
