Today as I'm doing an oil change I went to top off the oil in my Mercruiser 7.4 and mistakenly grabbed the quart of Mercruiser 90 gear oil for my drive instead of the engine oil. As it started pouring into the funnel I saw it was blue and immediately stopped it, but I would say 1-2 oz made it in the engine. Do I need to pump everything out or is that small amount mixed with the new engine oil on my 7.4 not going to hurt anything?
