Hi my name is Tan I will assist you.

Where is the water in the engine. The water usually gets in through the exhaust system. But I need to know if there is water in the cylinders, oil or fresh water cooling system.

Remove the riser inspect the exhaust and riser water passages for deterioration in the area where the 2 parts bolt together. If the risers have more than 350-400 hours on them they should replaced. The area where the riser meets the manifold is where the failure will be. If the manifold shows any signs of degradation replace them also. Drain the coolant check risers and manifolds replace as needed. If you have to replace the risers and manifolds your looking at around $1,000.00 in parts and 4-6 hours labor for replacement. These are Mercruiser style manifolds, I would use Mercruiser manifolds and risers. Here is a link to parts that you can use, these are Mercruiser parts. click here
