Question

What is the most powerful outboard engine u can buy for a power boat.?

Answer 1

Yamaha 350 four stroke. It is 800 lbs but it's a 5.3 liter V-8. They redline at 6000 rpm and the rev limiter stops it at 6250. Power is great and it will hold together better than a DFI two stroke or a supercharged POS verado.

Answer 2

The Mercury 2.5 EFI Champ.  It is a 2.5 liter V6 that produces 300 HP and turns 8800 RPM at wide opn throttle.  Although the Yamaha is rated at 350 hp, it is probably only limited to about 5500 - 5700 rpm.  Also the Mercry weighs 275 pounds and the Yamaha weighs 800 pounds.  That is a 525 pound difference.

Answer 3

The new yamaha outboard rated at 350 hp. Racing motors would have more.

Answer 4

The new Yamaha F350 V8

Answer 5
