My oil feed to gearbox and return to sump were aluminium tube. The group
advised that there had been failures due to vibration fatigue, so I have
changed them all to the flexible type. My 2.85 drive has now done 9 hours
with the thrust bearing and oil feed modifications. No leaks yet and is
maintaining 3mm play at prop. tip. Prop. speed of 2000rpm gets me along at
130knots. (gps checked) Waiting for more engine hours before full power
check. PS. oil air inlet is 4" not 3".
