Quicksilver Oil Filter for MerCruiser V6 Engines (Block-Mount, Part 35-883702Q)

The Quicksilver 35-883702Q is part of Mercury Marine’s lineup of oil filters, and it is designed to keep your MerCruiser V6 (4.3L) engine in top shape. In many boats with MerCruiser V6 engines, the oil filter mounts directly to the engine block – this filter is made exactly for those setups. By using it, you get factory-quality filtration as intended by the manufacturer, meaning your engine will receive the right amount of clean oil at every start-up and throughout operation.

Here’s what makes this filter outstanding:

• Made for MerCruiser V6 Compatibility: If your boat is powered by a MerCruiser 4.3L V6 – whether it’s an older carbureted model or a newer fuel-injected (MPI) version – and the oil filter screws onto the block, the Quicksilver 883702Q is the correct choice. (Note: V6 engines with a remote-mounted oil filter use a different filter model.) This ensures you’re using the exact replacement the engine was designed for
• Keeps Your Engine Healthy: The powerful V6 engines are often used for towing water skiers, fast cruising, or in heavier load conditions. The 883702Q filter captures the dirt and metallic particles that can circulate in your oil, especially at high RPM. This prevents scratching and premature wear of bearings, camshafts, and valvetrain components, thus preserving engine health
• Ensures Trouble-Free Startups: Thanks to its anti-drainback valve, the filter holds some oil and doesn’t let it all drain back to the sump when the engine is off. So on your next startup, the oil pump instantly builds pressure and sends oil to all components. This is especially important for marine engines that are started and stopped frequently – it virtually eliminates dry starts, which can be very damaging
• Built for Marine Conditions: The filter’s housing is corrosion-resistant, which is critical in the humid and salty marine environment. Whether you operate your boat in fresh water or saltwater, this filter withstands the elements. Its heavy-duty construction prevents deformation or bursting, even under high oil pressure during cold starts
• Easy Replacement During Service: With its compact design and standard threads, the filter is easy to change – simply unscrew the old one, apply a thin coat of oil to the new filter’s rubber gasket, and screw it on hand-tight until seated. Performing regular changes – at least once per season or per Mercury’s recommendations (usually every 100 hours) – will ensure your 4.3L MerCruiser stays well-lubricated and dependable

By using the Quicksilver 883702Q, you maintain the high performance characteristics of your MerCruiser V6 engine. This filter is often the recommended choice for powerboats in the 18–22 ft range (5–6.5 m) equipped with 4.3L engines – from sporty runabouts to small cruisers. A genuine filter provides peace of mind that your motor is receiving the best care, helping you avoid costly repairs caused by poor filtration.
