Howdy, Bemartin.<br /><br />We have a seperate forum for I/O and Inboard engines. You will have better luck there.<br /><br />Moving this there.<br /><br />Good luck.
Not sure how much detail you need but this is a great place for parts schematics. www.mercruiserparts.com<br /><br />If wiring diagrams are needed, the Clymer manual for Mercrusier specific to your year and engine/outdrivve is a complete source.
