where to install WP relief valve
I have a 98 312 fastech w/ stock 502 mpi's, At wot one engine is running at 30-33lbs of water pressure and the other is 28-30. I think I need to install relief valves but do not know where to plumb them in.
thanks

That would be ideal, but my 2000 502mpi's also run into 30-35psi range. They had 250hrs when I bought the boat and now have close to 600hrs on them.
I thought about adding relief valves, but figured its been fine for a lot of hours the way it is.

up to 35 is not too much of a concern, however if the boat were any faster it might be... rather than a pressure relief valve my suggestion would be to trim your water pickups a hair... start with about .030 off the deepest part of the tip... I'm sure this will help reduce your pressure to an acceptable PSI
