So everyone who has a newer model Mercury mine being a 2021 200 hp knows what a hassle it was getting that stupid piece out of the engine to get to the flush out hose. Then getting it back in was a bigger challenge uggh!! This piece fits in that hole perfect now just pop off cap push the hose on it and your done. The hastle I used to have to go through seriously kept me from flushing motor many nights well that's over now. Well worth the money so I highly recommend it.
