Does the Yamaha 25 hp outboard have fuel injection?

Yes, the Yamaha F20 and F25 both feature a Battery-Less EFI system. Both of these motors give you a reliable “first pull” start and optimized fuel efficiency, no matter the weather or altitude.

Can I upgrade my manual-start Yamaha 15 or 20HP to electric start?

While it's possible to upgrade your engine, it’s much less hassle to buy a ready-made model already tailored to your needs. RJ Nautical provides multiple configurations with reliable factory-installed electric starts.

What is the recommended maintenance schedule for these Yamaha portable outboards?

For optimal performance, Yamaha recommends breaking in your motor for at least 10 hours and completing an important Break-In Service at 20 hours. After this initial stage, you should get routine maintenance every 100 hours or annually, depending on usage. Maintenance services often include changing the oil, gear lube, spark plugs, thermostats, water pumps, and other important parts. However, some boat owners may choose to only inspect specific parts.
