SeaSierra 100-150 HP Heavy Duty Engine Cover
The SeaSierra engine cover is made of polyester fabric that shields the boat motor from wind, sand, rain, and sunlight. It helps prevent scratches and sun damage while reducing engine exposure during storage or transport. The size 29.1″x17.7″x22.8″ fits most 100–150 HP outboards. It is compatible with mainstream brands like Honda, Yamaha, Mercury, Suzuki, and Tohatsu, with horsepower listed for reference only.

Sized at 26.77″x15.75″x20.87″, it targets most 60–100 HP outboards and is broadly compatible with Honda, Yamaha, Suzuki, Mercury, and similar brands. The note about horsepower being reference emphasizes measuring for best fit. Choose this for smaller-to-midrange engines needing robust, budget-friendly protection.

Buying Guide: Key Purchase Considerations
Size versus fit matters most. Always measure your engine or hull dimensions and compare with the product’s listed measurements to avoid a loose or tight fit that fails to protect properly.
- Material and durability: Look for heavy-duty fabrics (600D or similar) with weatherproof coatings for extended outdoor use.
- Weather protection: Consider UV resistance, waterproofing, and breathability to prevent moisture buildup and mold.
- Ease of use: Quick-release buckles, adjustable straps, and easy-on/off design save time during seasonal storage or travel.
- Compatibility: Check that the cover accommodates your engine’s horsepower or your hull’s length and beam; horsepower alone is not a guarantee of fit.
- Ventilation: Some models offer breathable fabrics; this reduces condensation under the cover during storage.
