I have systems diagrams
Bud,The owners manuals have pretty much generic stuff and are not much help. They talk about tuning the rig, adjusting the stuffing box, changing the filters, etc, but stuff that is not specific to your particlar boat. You can find an engine manual for the Yanmar through dealer sites. If you send me your email address (look me up in the owners directory)I can send you a .PDF file with all of the boat specifications, wiring, plumbing and other diagrams.J. Tesoriero"Diamonds" H340
