Hi there, I just received 1995 Mercury 150hp 2.0 Liter, I did a compression test. From left side first and top to bottom:<br /><br />1) 115<br />2) 116<br />3) 0<br />4) 116<br />5) 115<br />6) 115<br /><br />piston number 3 there is no compression at all, you see the piston moving back and forward but there is no compression, the gauge on the tester dont even move, I found it very strange on why there is no compression at all.<br /><br />Any help or advice on this motor I will really appreciate.<br />Thank you
