installed new exhaust manifolds (rev marine) water pressure went from 18 to 30 wot. if i remove 1 of the 1/2inch pipe plugs on each manifold and install some sort of adjustable valve with it dumping overboard would it lower the pressure to be safe.

The pressure rose because the exaust is restrictive. It would be best to try to find the restriction and remove it. Anyways, I have a single 1/2" dump valve and it works great on my app.

I'd call the manufacturer and ask them why the tail pipe is causing a restriction. It might be as easy as opening up the water dump hole into the tailpipe. If you have to go with a pressure relief valve Merc makes one. http://www.offshoreonly.com/forums/s...water+pressure
Wett Vett on the board has one also.
