Buying Guide: 70 HP Outboard Motors And Accessories
- Engine compatibility: Confirm your engine’s exact model, year, and mounting pattern before purchasing trim/tilt components, props, or filters.
- Intended use: For recreational boating, prioritize efficiency and reliability (trim/tilt and propeller choices). For workboats, durability and easy maintenance (pump kits, guards) matter more.
- Performance vs. cost: Aluminum propellers offer affordability; consider stainless options if you need higher strength and adjustability, depending on your boat and load.
- Maintenance schedule: Regular checks of water pumps, fuel filters, and trim/tilt mechanisms reduce downtime and extend engine life.
- Protection and safety: Propeller guards help prevent damage during storage and transport; ensure proper sizing to avoid interference with the propeller hub.
