GL: engine over heating

[Jerry Weber]

Place your hand on the exhaust elbow or better yet use a heat gun if 
available. If the exhaust elbow is hotter on one engine then the other it is 
a good possibility that the hotter one is clogged. Salt water remaining in 
the exhaust elbow after shut down is boiled away by the remaining heat until 
engine cool down. Therefore you end up with crystallized salt in the small 
holes inside the exhaust elbow where the engine cooling water merges with 
the hot engine exhaust on it's way to the muffler and eventually exits the 
stern. If you find salt build up inside the exhaust elbow it can be boiled 
out using Muratic Acid. Be careful using this product and follow all 
directions to the letter, it is nasty stuff, do not inhale.
