Tilt Trim Cylinder End Cap for Yamaha, Suzuki, Honda, Johnson/Evinrude & Tohatsu Outboards

Product Details

This Tilt Trim Cylinder End Cap is a replacement hydraulic cylinder cap for selected marine outboard tilt and trim systems. Company catalog data lists applications across Yamaha, Suzuki, Honda, Johnson/Evinrude, and Tohatsu outboards. It is sold as a single end cap, not as a two-piece kit.

Use the manufacturer and reference number on your original cylinder cap to confirm fitment before ordering. The references below are catalog-listed applications for this end-cap design; they should not be treated as universal compatibility for every outboard in the same horsepower range.

• Replacement tilt trim cylinder end cap for marine outboard hydraulic systems
• Single-piece sale; seals, O-rings, hardware, and other service parts are not included unless separately specified
• Catalog-listed applications range from approximately 60 HP to 300 HP, depending on the engine family and cylinder assembly
• Suitable for service work when the existing cap is damaged, worn, or being replaced during hydraulic cylinder maintenance

Reference Part Numbers

The following manufacturer and aftermarket catalog references are associated with the listed applications. Confirm the exact number and cylinder configuration before purchase.

What's in the Box

• One tilt trim cylinder end cap

Seal kits, O-rings, retaining hardware, and other hydraulic components are not listed as included. Please verify the condition and required service parts for your cylinder before disassembly.

Installation Notes

1. Place the outboard in a safe, fully supported position and follow the engine manufacturer's procedures for tilt and trim service.
2. Relieve hydraulic pressure and clean the cylinder area before removing the original end cap.
3. Record the orientation and inspect the cylinder threads, piston rod, seals, and mating surfaces for damage or contamination.
4. Compare the replacement cap with the original part and confirm the thread, profile, and reference number before installation.
5. Install new seals or O-rings when required by the service procedure; they are not included unless specifically stated.
6. Start the cap by hand to avoid cross-threading, then tighten it according to the engine manufacturer's service-manual specification.
7. Refill or bleed the hydraulic system only as directed by the manufacturer, and check for leaks through the full trim range before returning the boat to service.

Troubleshooting & FAQ

Is this an adjustable pin wrench?

No. The original page incorrectly described this product as an adjustable pin wrench. This listing is for a single tilt trim hydraulic cylinder end cap.

Which outboards can use this end cap?

The company catalog lists selected Yamaha, Suzuki, Honda, Johnson/Evinrude, and Tohatsu applications, including Yamaha F150, F75, F115, F300, and F350 applications; Suzuki DF115 and DF140; Honda BF75, BF90, BF115, and BF130; Johnson/Evinrude 115–140 HP; and selected Tohatsu 115–225 HP applications. Confirm the exact reference number and cylinder design before ordering.

Is this sold as a pair?

No. The standard listing is for one end cap. A separate two-piece listing may exist, but it is not the product described here.

Are seals or O-rings included?

They are not specified as included. Inspect the original hydraulic cylinder and obtain the correct seal components separately if required by the service procedure.

Can I determine fitment from horsepower alone?

No. Several cylinder designs may be used within the same horsepower range. Match the original manufacturer, model, cylinder assembly, and reference number rather than relying on horsepower alone.

What should I check before installation?

Check the cap threads, mating surfaces, piston rod, seals, and cylinder bore for wear, corrosion, contamination, or damage. Do not install the replacement if the related hydraulic components require repair.

Is this an OEM part?

This listing is for a replacement end cap associated with the reference numbers shown above. It is not represented as a complete OEM hydraulic cylinder assembly. Confirm the original part number and application before purchase.

What torque should be used?

The correct torque depends on the engine and hydraulic-cylinder manufacturer. Use the applicable service-manual specification; no universal torque value is provided for this listing.

Safety & Important Information

• Support the outboard securely before working on the tilt and trim system.
• Hydraulic components may retain pressure. Follow the manufacturer's pressure-relief and service procedures.
• Verify the exact original part number, thread configuration, and cylinder design before ordering.
• Do not reuse damaged seals, O-rings, or retaining hardware when the service procedure requires replacement.
• Professional installation is recommended when working on pressurized hydraulic systems.
