no better way to tell than someone who repowered from 275's to 300's on the same boat. It obvious that the 300 hp rating is on the low side...I received this via email last night:

"For whatever its worth for your members and team..

Just swapped out triple Verado 275s with brand new Verado 300s. The team at TNT Marine in Miami is just about the most qualified mechanics I have ever seen in my 20 years of boating.

The boat is a Donzi 38 ZFX. Prior to the switch, the engines were running 6300 RPM on Bravo 24 Lap Props. Top speed was 64.7 MPH (GPS). After the swap to triple 300s, we had to change out the center prop to a Bravo 26 lap prop. The new engines are turning at 6200 top speed. However, the boat’s top end is now 71. 3 MPH (GPS)."

I would guess it's putting out more than 300

closer to 320-330 hp

Wow that 38 Donzi is....SLOW....!

That boat weighs almost 14,000 lb. with fuel...maybe it's not so slow.

Lots of torque for an outboard
