a friend just dropped a valve in his boat. he has a egt on the number 1 cylinder right by the exhaust port which is the exhaust valve that broke.

i'm thinking his egt's were in the 1300 range

540 bbc.



1300 is about normal BUT it make a difference whether
the reading is 1" off the edge of the flange or 2"
and so on.... at work(when I was) I tried to get a standard
of 1" so we could ALL talk the same numbers.... now
days I use the EGT just for balancing the intake
runners and I put the end of the probe right in the
center of the port dead nuts on 1"... I use a set
of calipers to set it
