On the other hand if you took all this seriously you would never fly over water for at least six months of the year in a SEP without dry / immersion suites, a raft an EPIRB and be dunker current at the very least.
As a friend of mine pointed out, you have a miniscule chance of the engine quiting in a SEP over the water (based on the statistical evidence) and if you exclude running out of fuel and poor maitenance the chance is even smaller - than miniscule.
For all I know the risk of a heart attack is far greater, but how many of us carry statins to take immediately afterwards.
Not that I should be running this argument - I feel far happier in a twin these days
