Ok, so after fighting with installing a power steering cooler, my dumb ass finds out that I have a cooler in with the oil cooler. DUMB ASS...I thought it was just the oil cooler, the way it looked. Well anyway..long story short, its been boiling the fluid out of the power steering pump after I run the boat for a bit. Any reason why it would be boiling over the cap??? Also should I just go ahead and use the cooler that I have installed in the boat over the factory cooler in the oil/power steering cooler, and just cap the two lines in the oil/power steering cooler? Help quick...

might just have air in system. if you get the air out and it stops pushing fliud leave it the way you have it. cycle the steering several times at idle checking to see if the level drops if so there is still air in the system. at speed the air working its way to the top of the system will push the oil above it out of the cap and all over the engine bay.
