OMC 225 compression

[Roddles]

OK omc gurus Is it true that my 95 Evinrude 225 vindicator would have differing amounts of compression with number 1 and 2 cylinders and if so why?

Never heard that one before. #5 & #6 will be a few pounds lower because of the larger CC chambers built into the heads for those two. #1 - #4 should be approx the same. However, I don't know what that is because I've never checked it on a stock motor.

115 to 120 is normal for that year, 110 on the bottom
