They respond quickly to email questions. Not sure but I think they do have various kits and one may well plug and play for you. I replaced all. On mine, the other gauge was the speedo and the upgrade turned it into GPS, rather than the pitot type. It was worth that alone. As far as the install, knowing how to do it now, I could literally do it in 5 minutes easy.

M6 all the way for sure. There would have to be a lot else about that boat that I don’t like to choose the 450. It was a good option during its time but compared to the m6 it’s no contest.

Just checked the supercharged LT4 compression test specs since I was curious. For that engine it is a minimum of 100psi and a 70% difference.

Supercharged and turbo motors are typically lower compression.

23mxz has had the same hull since debuted until it was redesigned in 2024

So if I get the TRD giages is there a kit to only have the speedometer and 4 in 1 guage or do I gotta buy all 3 and and is there a way to still get all the info that was on the oem speedometer?
