milk and reversion
 

I want to lenghen my tail pipes out the transom as I'm getting reversion now with new engines. I'd like not to make them dry. Should I have all the water dump at the end or release just enough and dump the rest. some info: 30 velocity(old) 600hp 509's , shorty hardin headers, stelling tails(4'' id) 28" long , 7" rise. Everything just pressure checked good, engines exhaust bla blah. 99% sure getting reversion. no time to send to pro shop.
gonna use local welder. Need advice on tail pipes
