Hey guys. Pretty new to boating and in need of advice. I bought a b100 and am having a hell of a time getting water to the top. New impeller checked and double checked for damage. Can’t find any blockages. Air will move through all jackets just fine. I took the intake manifold off and everything looked ok other than it had no stat. And everything seemed to be working ok until a road trip. I’m getting tired of pulling out my hair.
