Mercruiser 5.7 Liter 350.
I took "most" of the oil out using a junky walmart oil pump, pumped it till none came out anymore.
But it felt like only 2 quarts came out of the engine.
I added 4 quarts of straight 30W oil, and now the oil level shows full on the dipstick, while on trailer.
Should I take the reading while the boat on the trailer, or in the water, if over the full marker while in the water, should i take some of the oil out of the engine?
Thanks
