I found this round head phillips screw (see picture) laying in the bottom cowling - it is identical to those used to hold the plastic cover over the CDI unit. The part number for that screw is 90159-06M03-00. Is there a way to search for other occurrences for that same part number? I have checked every component that is visible, but have not been able to find any parts that are missing a screw. I don't want to be offshore and have a part fail because it has come loose.<br /><br />The engine model is LX150TXRY which is a 2000 year 150hp OX66 Salt Water Series II<br /><br />Any help or suggestions? Thanks!<br /><br />
