The other day while on muffs i lost water to the port exhaust. I just drug it back out of the garage today hooked up the muffs and now neither exhaust has water. Took off muffs and filled a tub with water and dropped the outdrive in and still nothing. I took of my power steering cooler on the exit side and water was coming out but not to forcefull (really not sure how much force should be coming out). Just wondering if these are symptoms of the impeller going out or could it be the steering cooler failing and causing obstructions. This is a OMC stringer
