If that model number is really E140TRLCIN it is a 1981, Christine.<br /><br />Compression should be over 100 psi measured with a screw in guage, warmed up engine, throttles open, 5 or more revolutions.<br /><br />That is not the important number, however. The important number is the range measured over the 4 cylinders. That spread should not exceed 15% of the average.<br /><br />Good luck, and welcome to iboats. :)
