Joe,
In 1969 I had the 6-71 on the boat checked out and the next day we nearly
sank the boat because a bolt on the heat exchanger backed out. Allowed a
stream of water 1/4" in diameter to flood the boat.
We used a professional mechanic, but he did not tighten one bolt of about
20 bolts down enough and the hole that it opened went straight into the
salt water supply.
There are more ways to shoot yourself in the foot than I can think of.
If I had it my way all the boats would be instrumented fully, but you can
imagine the impossibility of that.
If anyone has a water cooled exhaust and they go into the open way
offshore, the exhaust line should have alarms in it.
Did fatigue enter into this mistake? Sounds like it may have. In delivery
work, fatigue is the constant factor which is always just nearby. It is a
constant balancing act between forging ahead in order to get things done
and taking the time to get enough rest, which slows one down and prevents
making headway.
