Mercury – Quicksilver 8M0175441 Automatic Transmission Fluid | Marine Transmission Series | Premium Fluid | 8M0175441

Overview

If you’ve spent enough time on the water, you know that a transmission that shifts cleanly can make or break a day. There’s something reassuring about feeling your boat slip into gear without hesitation, whether you’re easing away from the dock in the morning or lining up for a pull with a Tow Sport boat full of riders. With Quicksilver Automatic Transmission Fluid 8M0175441, that smooth, confident feel becomes something you can count on. It’s built for the constant demand and unpredictable conditions that come with marine use, giving you one less thing to worry about when the wind and water start changing their mood.

Key Features

• Formulated for outboards, inboards, and Tow Sport transmissions requiring Dexron III
• Engineered specifically for harsh and variable marine environments
• Enhanced friction durability for smoother, more consistent shifting
• Low-viscosity blend to support better fuel efficiency
• Resists breakdown from high heat and heavy load cycles
• Maintains proper lubricity under long idle times and frequent gear changes
• One-quart bottle for routine maintenance or topping off

Engine & Boat Compatibility

This Mercury Marine part is suitable for:

• Outboard and inboard transmissions requiring Dexron III fluid
• Tow Sport boats designed for watersports and heavy load acceleration
• Pleasure crafts, runabouts, pontoons, wake boats, and general recreational vessels
• Engines and gearboxes that face repeated shifting, towing, or high-RPM operation

Always refer to your engine or transmission manual to confirm fluid requirements.

Performance & Practical Benefits

Marine transmissions work harder than their automotive cousins. They face sudden throttle changes, long idle periods, and constant exposure to moisture and heat. This fluid is built to handle all of that without losing the smooth feel you expect from a well-maintained drivetrain.

You’ll notice quicker, cleaner gear engagement and fewer harsh transitions when shifting under load. The enhanced friction durability helps the clutches inside the transmission bite properly, which is especially important on Tow Sport boats pulling riders, tubes, or heavy loads. The low-viscosity formula also helps the transmission run cooler and more efficiently, reducing stress when you’re cruising for hours or running tight maneuvers in choppy water.

This blend resists the kind of heat-driven breakdown that can rob a transmission of its protection. Even after long weekends, extended towing, or sitting between trips, the fluid maintains its stability and lubricity. That means parts stay cleaner, friction surfaces stay protected, and your transmission stays reliable season after season.

Why Buy OEM

Choosing an OEM-engineered product is like choosing the experienced mechanic who knows your engine inside and out. This fluid is tested to Mercury Marine’s strict original specifications, not general automotive standards. It’s built for marine duty — the constant moisture, the unpredictable heat cycles, the long idle times, and the unique demands of waterborne transmissions.

Aftermarket fluids may claim compatibility, but they rarely match OEM consistency or long-term stability. If you rely on your boat for family trips, watersports, or simply the peace that comes with time on the water, using the correct OEM-grade fluid is a smart, long-view decision. It protects your gear, preserves performance, and saves you from expensive repairs down the line.

FAQ

Q1: Which engines or systems does this product fit?

Any outboard, inboard, or Tow Sport transmission requiring Dexron III fluid.

Q2: How is it different from aftermarket transmission fluid?

It’s engineered for marine-specific heat cycles, moisture, friction behavior, and long idle periods.

Q3: How do I confirm this is the right replacement?

Check your owner’s manual for Dexron III requirements or match your current fluid spec.

Q4: Is this suitable for saltwater and freshwater use?

Absolutely — it’s designed to handle corrosion challenges from both environments.

Q5: Is installation straightforward?

If you’ve performed a transmission fluid change before, this will feel familiar. Always follow manual instructions for proper fill and level.
