454 has ticking noise
Started up the boat today and my starboard motor has a ticking noise along with the starboard bank running rich. It's probably gonna go to the mechanic soon, but anybody care to speculate what my problem is? Engine is a gen 6 330 mercruiser. Seems to idle a little rough as well. Oil is clean and has no water in it.
Thanks for any help guys

I does to me, but I can't be sure. Makes a double tick noise, stumbles a little when you give it throttle, but cleans up as throttle increases. Starboard side exhaust tip had soot all around it on the transom, other 3 tips were clean.

First thing, do a compression check and isolate the cylinder.
Could be a number of things; broken rocker arm, broken valve spring, stuck valve, bent pushrod (along with one of the other problems), collapsed lifter. Again , compression test is gonna be the first thing to do.
