I changed the spark plugs on my boat and this boat has had a bit of a misfire since day one honestly. Anyways, lately it's been getting worse. So yesterday when I was changing the spark pugs I could have sworn some metal shavings or something came out with the spark plug when I removed it. Whatever it was dropped into the bilge to never be found again. It's possible it was some paint that flaked off. idk. I didn't get a chance to check for spark, but I did go and get a borescope from advanced auto and didn't see anything unusual. Lots of carbon on the piston, but all the cross hatching is still on the cylinders. What are the chances of their being some debris leftover from when they machined the heads? the engine only has 150hrs
