exact oil for my boat...specially made for boats
I say that, because you might think that this is pricey for "regular" motor oil. It is not regular. This oil had additives in it that help suspend water. Why? well, the reason is that if you are out to sea, a long way from home, and you blow a head gasket, this oil will suspend and absorb water, and keep your engine lubed until you get back. Case in point...I had a leak in my intake manifold that filled my crankcase with water. When I checked the level, it was 3 quarts over full, and white soup. The water wasn't just sitting in the bottom of my oil pan, getting sucked up into my main bearings as water, and cooking all the internals. The engine ran just fine all the way home. This is why you use genuine boat parts!

Correct oil for Mercruiser 4.3LX V6. Since the engine takes around 4.5qt, I bought this in addition to the 4qt jug of the same stuff.
