I worked on aircraft for years where Murphy’s Law abounded. Basically this says that anything which can be fitted incorrectly will be. I put a new
water seal into the
water pump">raw water pump of my little
Volvo diesel. On restarting the
engine there was zero water output from the
exhaust. Fault finding: cover off impeller
engine turned over, impeller turns. Remove exit pipe from
pump and turn over engine, no water. Fill
raw water strainer with water, drains out of
boat inlet. Scratches
head, oh dear,
pump on upside down. Kicks oneself around the Marina.
