50810-S3Y-J01 rear. This one seems to go out much more often than the first two. I bought mine (genuine Honda only) from Autohausaz, as it was the best price I could find and I've had good experiences with their customer service.
50820-S3Y-J01 starboard. Shows up in catalog for CVT, but description is "Rubber Assembly, Engine Side Mounting (Mt)". Given that it bolts to the engine, whose position presumably doesn't change, it should be the same. Scott or anyone else - can you verify? 50805-S3Y-J91 port 50810-S3Y-J92 rear
Well when I grew up, it was in a boating family. We had a boat and so did my grandfather who had boats most of his life. He taught me at an early age about port and starboard and the color lights associated on the sides of the boat. The way he said to remember them is:
Port, left and red are all 4 letters or less.
Starboard, right and green are all 5 letters or more.
Cool, I didn't know that. Had vague memories of reading about aircraft carrier landing lights that were color-coded for sides.
I use port and starboard because unlike left and right, they're unambiguous with regards to where you're looking from. The left side of the engine bay is different if you're sitting in the driver's seat than if you're looking into an open hood. "Passenger side" and "driver's side" is unambiguous until you take right-hand-drive (UK, Japan, and some other countries) into account.
