Re: rusty 3.0

If you think there is a problem with the manifold, take the elbow off, make a plate to fit over the exhaust opening with a hole drilled in the center to vent the exhaust chamber and with a new gasket cover it, plug the water intake with something and pump air into the drain (about 15 lbs. I use my lower unit tester)if it holds pressure its good. Look the elbow over good, then turn it upside down and carefully fill the water jacket with fuel oil, if it doesn't leak into the exhaust chamber your good to go--Bob
