Parts and consumables for engines

The Quicksilver 883702Q is a replacement oil filter specifically engineered for MerCruiser V6 inboard/sterndrive engines where the oil filter mounts directly on the engine block. This OEM filter ensures optimal oil filtration and engine protection, with seamless compatibility:

• Application: Fits all MerCruiser V6 (4.3L) gasoline engines with standard engine block-mounted oil filters (no remote oil filter system) – e.g., 4.3 MPI, 4.3 carbureted models
• OEM Quality: Genuine Quicksilver/Mercury part (#35-883702Q) that meets factory specifications for filtration efficiency and oil flow rate
• Anti-Drainback Valve: Built-in valve prevents oil from draining when the engine is off, ensuring immediate oil pressure and lubrication at start-up – eliminates harmful “dry starts”
• High-Efficiency Media: M-pleated filter media traps fine particles and sludge, shielding your engine from wear even under demanding operating conditions
• Rugged Construction: Heavy-duty metal canister (50% thicker shell than standard filters) with a corrosion-resistant finish – designed to withstand the marine environment and provide long service life

The Quicksilver 866340Q03 is a versatile oil filter compatible with most gasoline MerCruiser engines built on GM blocks. From the 3.0L 4-cylinder up to V8 models and even Mercury’s new 4.5L/6.2L engines, this genuine filter delivers reliable filtration and protection:

• Wide Compatibility: Suitable for MerCruiser GM-based engines – 3.0L L4, 4.3L V6 (with remote filter), 5.0L, 5.7L, 6.2L V8, as well as Mercury Marine’s new 4.5L V6 and 6.2L V8 engines. Not for V6 with block-mounted filter (use 883702Q for those)
• OEM Quality: Genuine Quicksilver filter #35-866340Q03 meets factory requirements for oil flow and filtration – ensures your engine receives the correct supply of clean oil at all RPM ranges
• M-Pleated Media: Special multi-pleat filter design traps microscopic contaminants, protecting moving parts from wear. Keeps oil cleaner for longer even during extended engine operation
• Robust Build: Tough steel casing with corrosion-resistant coating – ideal for the marine environment. 50% thicker walls than standard filters, handling high oil pressure and vibration with ease
• Anti-Drainback: Equipped with a valve to prevent oil drain-out, providing instant lubrication upon startup and guarding against dry starts – particularly important for high-revving V8 engines
