hey guys was wondering if i could get some help. i have a blown jet boat with lightnings, i just noticed water in the oil. removed the headers, they look good. i dont think the head gasket is blown it is copper. my question is if i am plumbed correctly. -8 of the pump tees into 2 -8's into each side of the block, a -8 comes out of each side of the bds manifold and tie into a remote water manifold, the remote then feeds each header w/ a -8 line and the remote manifold also has a -6 line going to a dump. the motor never runs over 120. but i am wondering if may the pressure is to high. what is a safe water pressure to run to the block. never had a problem before when running bassets.
