I hope you talking about an inboard engine here. The question is kind of vague. Mercury also makes outboards of this size. For an inboard, it's PROBABLY a Chevy 4 cyl. and PROBABLY take five quarts when you change the filter too. Change the filter, put in 4 1/2 quarts, let the engine idle (with water going through the pump) for a couple of minutes, then check the level on the dipstick. Add more if you need to now.
