Hi,<br /><br />I have just bought a boat 1992 w/ 3.0 mercruiser engine. <br />I saw ther e were rusted areas around the spark plug, but the<br />plug looked normal. I read may topic about the water infestation<br />that can cause a suden death to the engine. <br />What is the normal cost the replace the manifold and riser?<br /><br />Thanks in advance,<br />BC

You don't want to know......<br /><br />Check Mercury Parts Express, just enter your serial # and if will give you breakdown of parts.<br /><br />Sit down, take 2 aspirins (helps during heart attack) and scream...

From West Marine exhaust average $300, Riser average $125. Check here or on the net and may find a better price. If you run in salt water average life is 4 to 6 years if you flush engine real good. If you get water to the exhaust valves or in the cylinder it is ugly.
