- Place a suitable oil drain pan beneath the hydraulic pump and cylinder connections.
- Carefully disconnect the old hoses at both the trim cylinders and the connector block, noting their routing.
- Install the new hoses, ensuring the port and starboard lines are connected to their correct positions.
- Tighten all fittings to the manufacturer's recommended torque specifications; do not overtighten.
- Fill the hydraulic fluid reservoir with the appropriate trim/tilt fluid.
- Reconnect the battery and cycle the trim/tilt system 5-10 times to bleed any air from the lines.
- Check the fluid level again, top off as needed, and inspect all connections for leaks.
Troubleshooting & FAQ
How do I confirm these hoses will fit my specific MerCruiser model?
The key is to verify your sterndrive model and year against the compatibility table. This kit fits Alpha One (Gen 1 & 2), Bravo (1, 2, & 3), and older R/MR drives that use 16-3/16" long trim cylinders. Cylinders with casting number 14035-1 are also compatible.
What are the signs that my existing trim hoses need replacing?
Common signs of failure include visible fluid leaks around the fittings or along the hose, cracks or bulges in the hose casing, and a spongy or slow response when operating the trim/tilt system. Any visible damage warrants immediate replacement.
Can I replace just one leaking hose, or should I replace the whole set?
For optimal reliability and performance, it is highly recommended to replace all four hoses as a complete set. Hoses degrade at a similar rate, and replacing only one may lead to another failure shortly after.
What is the difference between these hoses and the original OEM parts?
These are aftermarket hoses designed to meet or exceed OEM specifications. They are made from comparable high-quality materials, such as braided stainless steel, to offer similar performance and durability to the original MerCruiser parts but at a more accessible price point.
How often should trim hoses be inspected or replaced as part of routine maintenance?
We recommend a visual inspection of all hydraulic hoses at least once per season. As a general guideline for preventative maintenance, consider replacing the hoses every 5-7 years, depending on usage and environmental conditions (e.g., saltwater vs. freshwater).
What type of hydraulic fluid should I use with these hoses?
Always use the fluid recommended by your sterndrive manufacturer. Typically, this is a high-quality power trim and steering fluid. Check your owner's manual for the exact specification to ensure system compatibility and longevity.
