Re: Oil and water mixed
Hello and welcome to iBoats.
Oil in the water is never a good thing. Just to set your mind at ease. This 'marine' engine, is just a normal 350 SBC with a few specialized marine bits on it... So all you petrol engine experience will help you...
The special marine bits are:
Starter motor
Alternator
Fuel pump, carb and fuel lines
Most of the ignition system
and the exhaust manifolds.
The electrical stuff is mostly the same, expect it's set up to be explosion proof.
ok.. Water in the oil. 2 main causes. 1, Cracked engine block, usually due to freeze damage, or 2. corroded exhaust manifolds, allowing water in the cylinders, which then leaks down into the crankcase/oil pan....
As you're new here, and to boats by the sound of it. Serial numbers are king with Merc products, so if you want specific help, please post your engine and drive serial numbers. As the boat and engine are made by different companies, the year of the boat has little relevance to the engine... Which is why we like serial numbers
