OK, I've gotten down to the root cause of my problem ('90 Evinrude 110). No compression on <br />cylinder 4. Meaning Zip. Nada. Zilch.<br /><br />Any hope for a miracle cure? I just bought it and it ran OK on land, but in the lake only 2500 RPM. Once it went to WOT, 50+ MPH, then back to no power. <br /><br />Sticky reed valve? Stick rings? Little spooky things hiding?<br /><br />Please help prevent a nasty situation withthe seller.<br /><br />Thanks,<br /><br />Doug
