Re: something new 4.3 lx GEN+ 1997
At this point don't crank the engine with the coil wire attached. You don't want the engine to fire if there is water in the cylinders, you can bend a rod! With the coil wire disconnected you can crank the engine and get the water out, better yet pull the plugs and blow out the water. Was the boat in the water when water entered the engine or did this happen w/ muffs on? Would help identify if it's sucking water back in from the "y" pipe or if it's leaking down from manifold/riser mating surface. By the way, how cold is it in Jax, Fl.?
