I think that's becuase most ETEC owners really haven't had many problems. I got my 90 ETEC over the winter and first ran in in January, I've been running it regularly without incident since. It's been flawless so far but for one incident with contaminated fuel, quickly resolved by simply switching tanks. I was impressed with how quickly and easily the ETEC recovered from that outside flaw.
I haven't had the motor back to the dealer and I have no hour meter, so I don't know how many hours I've put on it, but I'm very happy with the ETEC. I probably should take it in simply to have the hours checked. I'd have to guess I've put about 80-100 hours on. My boat gets about 5-6 hours/day at every regatta it goes to, most are 5-10 days, and it's been to about 5 regattas, plus a few play days
I'll probably put on another 150-175 hours by the end of October when the US Paralympic Sailing Team selection wraps up.
