In the early part of last year, I purchased a Sea Ray 280 DA. And as usual the previous owner did not update me with all of the current issues. In the process of eliminating these issues, I like everyone else here found out that our buddies at Mercruiser did not have any type of troubleshooting schematics. However being an Electrical Engineer, I started generating these schematics.

The schematic below will work for all mercruiser trim systems. If you have any questions, let me know and I will try to answer them.
