NMEA 2000 Shield

Hello,
I'm just about to start a project building a tacho, engine hrs, temp and display it on a Raymarine MFD. I have a couple of questions before I start and apologies if these have been answered before, ( I have been through the 28 pages and couldn't see it)

  1. Is it possible to connect the CAN bus directly to the SeaTalk bus?

  2. The MFD looks for an Engine manufacture when scanning for new devices, do I have to emulate my engine manufacture? (I have a Yanmar)

Many thanks for any pointers, help.
