Hello all,
Just bought a 2021 Shoalwater 21' CAT, w/ Suzuki DF200. My question is: Are there ECU programmers on the aftermarket that boost HP? If so, which ones are best?

I feel like the DF200 is a bit underpowered. I just sold a 22' bay boat style hull with a DF250. It was needless to say, way faster. I understand the CAT hull will never perform like the 'V'. I just want more power.

In short, no. Nizpro does tuning for Yamaha and there may be some individuals that can squeak some from certain Mercs but no tuning that I know of for Zuks. Google it, I may be wrong.
What are you getting for speed? How much adjustment have you played with in JP and trim settings? That boat with that motor should be low 40s I would think.

Congrats on that Shoalwater. Your boat isn’t a fast hull. Regardless of what motor or horsepower you’re not going to see a huge increase in speed. You can run fast and run shallow but it takes lots of dollars. Something like a SCB 24 would do what you’re looking for at around 125k.
