I think Andy meant 60K pulses per minute for the optical tachometer
(three bladed propeller ?)

If the prop's in the water I don't think the engine will be doing
much over 15krpm

The tacho would only need to measure up to 20krpm = or 333hz
(unless you use 25% fuel <G>)

Is it true that they have, on the new version of windows
managed to increase the MTBF from 95 to 98 minutes ?
(That's why they called it 95)
