I am thinking of switching to pre mix. Is it as easy as removing the oil pump and sensor. My motor is a 95 135hp mercury.<br /><br />Any suggestions

Hi, Tripp.<br /><br />Though I have been known to recommend disconnection of early OMC VRO systems, I would leave your Merc alone.<br /><br />The Merc system reliably delivers correct mix at all rpm. <br /><br />Premix is richer than required for low and mid-rpm so that it can be adequate at high rpm. Result: more smoke and oil consumption than necessary.<br /><br />Good luck. :)

The other side of that coin is that if that pump and/or sensor fails you will need to turn your wallet upside down and shake it real hard.
