Buying Guide: Key Considerations for Boat Lifts
How do I pick the right lift height? Measure the lid’s width and the available space when opened. Choose an extended length that fits without hitting rails or frames, and ensure the compressed length allows installation with room for mounting brackets.
What lift force do I need? Match the lid weight with the strut’s lift rating. For small hatches, 10–40 lb shocks are usually sufficient. For heavier lids or larger compartments, aim for 45–100 lb options while avoiding overkill that makes operation stiff.
Are brackets included? Some products include mounting brackets and screws. If not, verify compatibility with your mounting holes and ensure the screws fit your lid’s material.
Weather resistance matters? Look for all-weather lubrication and corrosion resistance, especially for boats that face sun, salt spray, or wide temperature ranges. Stainless or chrome-plated components enhance longevity.
Installation complexity? Most options install with basic tools such as a flat screwdriver. Check for any special mounting requirements and confirm lid alignment to prevent misalignment or creasing.
FAQ for Boat Lift Shocks
- What if my lid weight changes after installation? Choose a lift with a slightly higher rating to accommodate weight changes or added accessories. Avoid undersized shocks which can fail to support the lid.
- Can I mix different brands? Mixing brands is possible if the dimensions, extension, and force are compatible, but it’s best to use matched pairs to ensure even lifting.
- How do I install these with brackets? Align the brackets with screw holes, attach the struts, and test the lid’s travel; adjust if the lid overshoots or binds before fully opening.
- Will cold weather affect performance? Extreme temperatures can affect oil viscosity and response time. Choose strains rated for wide temperature ranges if you boat in diverse climates.
- Are these suitable for fiberglass lids? Yes, provided the mounting hardware is appropriate for fiberglass and the lid weight falls within the strut’s rated range.
- Do these struts require tools? Most installations need only a flat screwdriver; no special tools are required.
