Hi @janine22, how did it go with the 350? If you ended up with that size of motor in the 23 lsv, how did it perform for you? at this altitude? was it able to surf well with the boat loaded with people and extra ballast?

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.
