GHmarine Water Pump Impeller Kit for Yamaha 150–300 HP
The kit covers Yamaha 150, 175, 200, 225, 250, and 300 HP outboards, making it a practical pick for Yamaha-powered 250 HP boats. It includes a water pump impeller and housing, with compatibility across several Yamaha part numbers. This option is best for owners who prefer a direct Yamaha-centric repair kit and want to ensure consistent cooling performance. A potential limitation is that you should verify exact model compatibility if you have a non-Yamaha outboard in the fleet. Choose this if you’re maintaining a Yamaha 250 HP motor.
SeaSierra Boat Marine Outboard Engine Cover for 225–300 HP
This cover uses oxford fabric with PVC coating for tear resistance and weather protection. It guards against wind, sand, rain, snow, and scratches, while limiting sun exposure to reduce engine damage. Sized for most 225–300 HP outboards, it’s compatible with brands like Honda, Tohatsu, Yamaha, Suzuki, and Mercury. Note that horsepower serves as a reference; measuring your engine is advised to ensure a proper fit. Best for boaters needing sturdy, all-season protection for mid-to-high-range HP engines.
Zettum 600D Outboard Motor Cover
Designed for 250–300 HP motors, the Zettum cover uses 600D heavy-duty oxford cloth with a PU coating for waterproofing and tear resistance. It is breathable and softer than PVC equivalents, reducing heat retention under sun. The cover is easy to put on and take off, offering reliable protection against sun, dust, moisture, and debris. Best for owners who want a rugged, long-lasting protective layer with simple use. Consider checking the size chart to confirm a precise fit for your model.
TeBaisea Outboard Half Cover for 250–300 HP
This half cover is made from premium 600D fabric with waterproof and UV-resistant coating. It fits Mercury 250 HP, 300 HP, and 200–300 Pro XS 4-stroke V8 engines. The elastic tie-down straps provide a secure fit, while a soft felt lining protects the engine surfaces from scratches. Best for users wanting focused protection for high-HP outboards with a snug, easier-on/easier-off solution. A limitation is that it’s a half-cover design, so full engine exposure remains possible in certain conditions.
