The OEM fluid Yamaha designed for your trim & tilt

Keep your Yamaha’s PT&T running smooth with Yamalube Power Trim & Tilt Fluid (part ACC-PWRTR-MF-32, 1 quart). This premium, non-foaming hydraulic formula is engineered for high heat and pressure in marine trim/tilt and power steering systems – helping prevent aeration, chatter, and premature seal wear. Meets Yamaha’s factory requirements.

At-a-glance details

• Type: Yamalube Performance Power Trim & Tilt Fluid (hydraulic)
• Size: 1 quart bottle
• Use with: Yamaha power trim & tilt and power steering systems
• Benefits: Non-foaming; resists heat/pressure; smooth, quiet operation; reduced wear.

Quick how-to: check, top-off & bleed

1. Tilt fully up and engage the mechanical tilt lock/stop.
2. Remove the reservoir cap slowly (system may be under pressure). Fluid should be near the top with the unit fully raised.
3. Top off with Yamalube PT&T Fluid until level is correct; reinstall cap.
4. Cycle the engine up/down 4–5 times to purge air. Re-check level with the engine up and top off again if needed.

Safety: Wear eye protection; keep clear of the prop; never reach near rams when cycling.

Pro tip: Grease the tops of the trim rams periodically to deter corrosion and squeaks. Use Yamaha-approved marine grease.

What it is / where it’s used

Yamalube Power Trim & Tilt Fluid (ACC-PWRTR-MF-32) is Yamaha’s factory-approved hydraulic fluid for electric-hydraulic trim & tilt units on Yamaha outboards. It’s a non-foaming, anti-wear, anti-corrosion hydraulic oil blended for wide-temperature marine use and seal compatibility in Yamaha PTT systems. (1-quart bottle.)

Why use it (benefits)

• Smooth, quiet operation  –  resists foaming/aeration so pumps don’t cavitate.
• Protects internals  –  anti-rust/anti-oxidation additives help prevent pitting in pumps, valves, and rams.
• Marine-ready  –  formulated for salt/humidity exposure and long service intervals when the system is healthy and sealed.

Quick facts (spec/fit)

• Container size: 1 US quart.
• Applications: Yamaha power trim/tilt systems; also suitable for many marine trim/tilt units that call for a non-foaming hydraulic oil.
• Do not use in hydraulic steering systems that specify a dedicated steering fluid, automatic transmissions, or brake systems.
• Mixing: If a previous owner used ATF or non-spec oil, do not mix. Drain/flush and refill with one fluid type that matches your owner’s manual.

How to check & top up (summary)

1. Trim fully down (tilt rams retracted), key off.
2. Locate the fill/level plug on the trim/tilt reservoir. Clean around it.
3. Remove the plug and fill to the bottom of the hole with Yamalube PTT fluid. Refit plug.
4. Cycle trim up and down 3–5 times to purge air; let it rest a minute, re-check level, and top off if needed.
5. Inspect ram seals/hoses for leaks; wipe any residue.

Tip: Milky fluid = water contamination. Drain/flush and refill, then track down the leak before returning to service.

Signs you’re low or aerated

• Trim/tilt becomes slow, jerky, or noisy (pump “whine”/cavitation).
• Engine won’t hold its trimmed position and creeps down.
• Foamy or milky fluid at the fill port.
• Visible leaks at ram seals, hoses, or the reservoir.

Maintenance cadence

• Level check: at least each season and anytime performance changes.
• Fluid replacement: when contaminated, after major service, or per your Yamaha owner’s manual interval for your model.

Compatibility & alternatives (read first)

Yamaha recommends Yamalube Power Trim & Tilt Fluid for Yamaha PTT systems. Some legacy units and non-Yamaha systems may list ATF or a general hydraulic oil – follow your owner’s manual. Never substitute hydraulic steering fluid in trim/tilt systems (and vice-versa).

FAQs about  ACC-PWRTR-MF-32 (1 Quart)

Is this the right fluid for my Yamaha trim & tilt?
Yes – this is Yamaha’s OEM Yamalube PT&T Fluid (ACC-PWRTR-MF-32), formulated for Yamaha PT&T and power steering systems.

Can I use ATF instead?
Some Yamaha manuals (especially on older models) specify ATF Dexron II as acceptable PT&T fluid. If you’re switching types, it’s best to drain and refill one type, then bleed. Always follow your model-year manual.

How do I know the system is low on fluid?
Trim gets noisy, jerky, or won’t hold; cavitation/foam in reservoir; slow to raise. Top off and bleed per steps above.

Can this be used in Yamaha power steering?
Yes – Yamaha lists the same Yamalube PT&T Fluid for PT&T and power steering systems.

Is this fluid compatible with my Yamaha outboard?
Yes – this is Yamaha’s recommended fluid for Yamaha power trim & tilt units. Always confirm against your engine model/year in the owner’s manual.

How much fluid does the system take?
Capacity varies by model. Fill to the level of the fill port with the engine fully down, then cycle/bleed and top off.

Can I mix this with ATF or other hydraulic oils?
Avoid mixing. If you’re switching fluid types, drain/flush before refilling with the chosen fluid.
