i have a 1998 9.9 gamefisher i have some question i hop i can get some
help with.
1. approx how much compression should it have?
2. can you get an accurate reading by just pulling the rope? does that
spin it faste enough, long enough?
3. if one cyl is 30# less then the other, what might be the probable
causes be after head gasket has been eliminated? the cy wall looks
fine, no scratches, abrasions

i sure appreciate any help on this, i have really liked the
'spunkyness' of this motor and it ran well the past few years. my son
overheated it by backing in reverse for an extended period of time
while motoring around a small lake inlet.

thanks in advance.. -gary
