1999 Yamaha 200 salt water series 2 stroke V6

I have been experiencing intermittent lost of power on my outboard. I will be able to run at full throttle no issues one day and the next start off good then maybe hit a big wave and then lost throttle. It will run only at 12 rpm then stall if I throttle up and more or try to shift into reverse it will stall out.

I have replaced fuel filters fuel lines found a lose spark plug wire. Every time I think it’s good to go it works a few times then will lose power. Like there is air getting in some where. Any help.
