talking about mid to high eight-thousands and wonder how they are meeting the

don't see propping a two stroke above 8,000, they just get loud. (a 17-13N on a
two stroke 140 turns 7,700 or so and a 17-12 gets loud in the air ...
IMHO)</FONT></SPAN></DIV>
<DIV><SPAN class=108133217-29052003><FONT face=Arial color=#0000ff size=2>For
the 4-strokes, the cam just wakes up at 8,000 on both the YS DZ and
FZ, I would think that we should be playing with props that turn in the very low
8,000s.</FONT></SPAN></DIV>

<DIV>Has anyone measured the sound levels of the larger two strokes turning
the big props? We measured a YS140DZ with ES pipe turning a 17X12 APC
and came up with 96dB, right on the limit. Just
curious.</DIV><BR><BR>Bob Kane<BR>getterflash@yahoo.com
