Are you sure it's coming from the silent masters??? I had a simular noise coming from my 96 prostar 190 transmission, which is pretty close to the same area on the boat.

To help determine if it's the trany try seeing if the noise changes when in F, Nuetral and Rev. If you start to head in this direction here's what I found out. My marine mech ended up contacting MC about the noise and they said that it was normal. I didn't like that answer so MC recommended that a "dampener plate" be installed. Had it installed...no more noise.

Good luck.
