The alternator coupling in my IO550 powered ES gave up the ghost after 128
hrs. I believed
that it was defective in either design or manufacture, or both. Seeing two
recent post giving
similar experience just strengthens this belief. The factory was willing to
sell me a new
coupling for a mere $1425. They don't seem to know what warranty means.
Are there others who have had similar experience?
