Buying Guide
What matters most when choosing a 50 HP outboard cover or related accessory is fit, material, and ease of use. Consider the following:
- Engine size and model: Always measure circumference and height in addition to horsepower. Some covers specify ranges like 30–60 HP but fit differently depending on motor cowling and mounting hardware.
- Material and protection: PVC-coated Oxford fabric offers water resistance and durability, while PU-coated 600D fabrics offer breathability and environmental benefits. Choose based on climate (wet, sunny, dusty) and storage needs.
- Breathability: Breathable fabrics help prevent moisture buildup inside the cover, reducing mildew and rust risk. If you store the engine covered year-round, this matters more.
- Ease of use: Look for covers that are easy to put on and remove, especially if you frequently remove the cover for maintenance or use.
- Brand compatibility: Check compatibility with brands you own (Mercury, Yamaha, Honda, Suzuki, Tohatsu) to ensure a proper fit and protection level.
- Warranty and care: While not always included, consider care requirements (spot cleaning, drying) to extend the cover’s lifespan.
FAQ
- Q: How do I know which cover size to pick for my 50 HP engine?
A: Measure your engine’s cowling dimensions (circumference and height) and compare with the product’s listed size. Choose the cover that accommodates those measurements with a little extra room for a snug but easy fit. - Q: Are PU-coated covers more eco-friendly than PVC-coated ones?
A: PU coatings are generally considered more environmentally friendly and breathable, which can reduce moisture buildup inside the cover. - Q: Can these covers protect against sun damage?
A: Yes, most covers are designed to block direct sunlight, helping reduce sun-related engine wear and fading. - Q: If I have a Mercury engine, should I prefer specific Mercury-compatible covers?
A: While many universal covers fit Mercury engines, choosing a model confirmed to accommodate Mercury dimensions helps ensure a better fit and protection. - Q: Do these covers protect against snow and ice?
A: They provide protection against snow and ice exposure, but extreme winter conditions may require additional winterization steps beyond a cover. - Q: Is it okay to leave a cover on during operation?
A: No. Covers should be removed before running the engine to avoid overheating or damage.
