Sounds like 2 separate issues here. First, you bought a new boat, you deserve a new, flawless boat. I would probably accept it if the problems are correctable to my satisfaction. As for the electronics, if you got what you asked for but you didn’t like what you got, that would be your mistake but would expect the dealer to work with me to get the correct ones. If on the other hand, you just told them what features you wanted and they chose incorrectly, then it’s back on them to make it right. Generally if a person calmly explains their position, most businesses will do what they can to make it right as they can’t afford to lose future sales over 1 boat. I hope it works out for both of you.
