Qsb plug size in water pump (freshwater flush)

[Mike Mason]

I am setting up fwf system for a friend. I did mine but don’t recall the plug size on the water pump. We will be going in after the impeller so he can flush without the engine running. I verified today he has his exhaust set up properly. Mikelson 43.

Thanks.
