So I recently bought this 14 AR240 with around 104hrs. Boat is in great shape and test ran everything worked fine. Started to notice when I take it home to flush the engines out( I’m in brackish water) one engine sounds rougher than the other engine. Tried to attach a short video but I’m not too tech savvy lol. Noticed the rougher sounding engine has a tad bit of water out of the side pissers too while the smoother running one does not have anything coming out. Both have water out of the pissers when out in the water though. It didn’t really alarm me at first because BOTH of my 08 AR210 engines sounded similar with a rattle sound and wouldn’t have anything coming out the pissers when flushing. Any ideas?

PS checked the oil a while back when I started noticing it and oil level and color was good.
