There are about a dozen IO540C4B5's in the list and since one of ours was
overhauled in 2001, I had to contact Penn Yan to get the serial number of
the crank. No problem, it wasn't on the list.

ducked the bullet once again.


There are also a few -360 (4 cyl) series engines affected, specifically
those with counterweighted cranks. The IO-360-C1C6 in our Arrow IV falls
in
this category, and since we installed a factory reman last year I was very
worried until I looked up the list of affected SNs and crankshafts.
Fortunately, they used a refurbished, older crank (originally manufactured
before the March 1, 1999 cutoff) on our engine, so we dodged the bullet.
