i have been running this motor in my hull for around a year now,
and have to say. starts on every second pull if not first, runs great and never loses tune, good speed and hasn't stalled on me once.
yet i go out with mates with modded zen's and they are always hard to start and forever stalling out on the water.
the only problem i have ever had with the motor was the coil, which i replaced which a standard zen one, haven't had a problem since.
great motor
as for the other guys commits for them been cheap and crap engines, i beat they have never even seen they run or held one in there hands. its like the good one chev vs ford, your either one of the other.
well open your eyes, because there's more out there then just zenoahs
