454 330 engine noises!

Hey guys! Long time jetski guy, I just bought a 98 scabard 22 with a stock 454 330 with 460 hours on it. Bought it as a total project with limited historical knowledge. After doing oils and fuels and what not I started it up. It runs well, fires right up. But it sounds louder from the inside than I had anticipated. I’ll attach a video here. Does this sound like a knocking to you guys?

Ok, seriously now..we need a bit more description of the sound. Also, do you have any sort of Captain's Call/Silent Choice type of exhaust? On my boat the Silent Choice makes an odd sort of sound that is a ticking/rumbling/knocking sound...
