My problem is water in cyl # 8, 6, and 4. Replaced the head gasket last weekend. thats not the problem.
1981 Sea ray 260 hp (no serial # anywhere, I looked) MR-1 drive, log style manifolds with the hump riser at the rear of the manifold.
I disconnected the 3 hoses from the log style manifold and hung them in the bilge.
I ran the motor on muffs, no water in cylinders. If it were a cracked block or bad head gasket I would still get water in the cylinders? (I replaced the head gasket last weekend)
When I hooked up the 2 water lines to the manifold with the riser removed and the hose hanging in the bilge. I ran the motor there was water coming out of the square exhaust port on the manifold where the riser bolts on.
Then I blocked off the rear hose nipple and blew in the other (both ends of the log manifold)
Should I have pressure? When I block off on end and blow in the other I can hear air in the middle of the log inside what I think is the exhaust side of the manifold.
Should there be a seal between the water and the exhaust?
With the hose going to the riser disconected and hanging in the bilge, should water be able to enter the exhaust side of the manifold?
