Changing Spark Plugs ✨on a 1999 Mercury/Mariner 175 EFI Outboard 🚤🎣

🔧⚓ Wild Bill is back at it! Today he's changing the spark plugs on our 1999 Mercury/Mariner 175 EFI outboard motor to keep this classic V6 ready for more adventures on the water. Routine maintenance may not be glamorous, but it's all part of keeping the boat running strong. Let's see how the old plugs look and get this engine one step closer to its next fishing trip! 🚤 #MercuryOutboard #MarinerOutboard #Mercury175EFI #BoatMaintenance #SparkPlugs #DIYBoatRepair #BoatingLife #FishingBoat #WildBill #CalamityCrew
