How does water get in oil?
Water in the engine – Water can get into your oil sump in two ways: Water in car – Water condensation in cold air or combustion gases: this phenomenon is extremely rare and only occurs at specific temperatures. Water in the oil – Coolant leak due to non-watertight seal (cylinder head gasket, etc.).
What is the difference between marine gear oil and regular gear oil?
Marine gear lube, unlike automotive gear lube, is formulated to emulsify water. This serves two purposes: It provides consistent lubrication, keeping water away from moving parts. It keeps the lower unit from freezing (yours didn’t freeze last winter, did it?)
How can I tell if water is in my motor oil?
Bubbles on the stick, a brownish residue just above the oil level, or milky-brown oil with a thick consistency are all indications of water in the oil. Check for white, sweet smelling smoke coming from the tailpipe. This is an indication of coolant in the oil being burned off. Turn the engine off and let the vehicle sit for a few hours.
What does water in oil 4 stroke outboard look like?
The description states “after about 5 hours of use the oil looks a little milky” A head gasket, or maybe even the condensation mentioned is a easy fix, a crack in the block is not worth it.The add also mentions the good compressions and good idle and running.Trying to make a decision Thanks for the info.
What kind of oil does an outboard motor use?
According to Kelley, new motors coming from the factory in Fond du Lac are filled with the same 25W-40 mineral Mercury oil we can buy in a bottle. Engines smaller than 50 HP manufactured for Mercury in Japan are filled with a 10W-30 oil that’s blended in Japan.
Where does water come from in engine oil?
Oil is still slightly milky but clear. There is a small amount of water coming out of the manifold gasket just forward of the carb, right about where one of the bolts for the manifold is located. When the engine heats up the leak stops (at least on the outside). I checked the torque on the bolts and two were not as tight as the others.

What kind of oil do you use on an outboard boat?
“The VMAX SHO owner and some of our 4.2 Offshore owners, who really run their motors hard for an extended period of time. It’s also a good choice for the F115 and F70 motors, which can be run up to 6300 rpm.” Trolling in cold water might really be the toughest duty your outboard oil will ever see.
What happens to oil in an outboard engine?
During extended trolling an outboard may not reach normal operating temperature and even with modern fuel injection and engine controls, unburned fuel in the combustion chamber can condense and migrate past piston rings and contaminate engine oil, a situation engineers call “fuel dilution.”
