Canon EOS R6mii water damage

[ShabinIR]

My camera was damaged by a wave hit, while I was shooting surf. Some chips in the motherboard are damaged, I'd like to know how much will it cost if I sent that to a Canon Service Center and will it be repairable?

No idea.  If you've registered the product with Canon, look at starting a repair service which will most likely lead to getting an estimate.  You can then evaluate if such a repair would be worth it.
