Do you think their is enough positives to have this done or is the extra 50 HP not worth it?

No. I’ve heard a few guys running the NWT have done this and have been extremely impressed.

Here is a flyer to what the company is claiming.

There are companies that can reprogam the ECU to allow the motor to put out more horsepower, torque, and raise the rev limiters. Essentially turning a 250 HP motor to a motor that can put out up to 320HP.

It looks like the bravo 1 is the prop to try but how can a 19″, 20″ and 21″ all give the WX2060 the same results. From what I have read from three different guys is that they are seeing 57-58 mph at around 5800 rpm with different pitch props??

I tried a 22 but that did not work. I have read a 20 would even work. Have you tried that?

Garmin states you should be able to see 200 feet with forward facing transducer. Is that a stretch from what you have seen? Or are you stating you can see 25ft with the down view?
