Looking to buying my first volvo penta (99 Four Winns) after years with a Mercruiser. Going to fire it up pre-sale and need to do a quick drain job as we might still get a light freeze in IL. Trying to learn from prior posts. From reviewing posts it looks like there are 2 block drain plugs and 2 manifold drain plugs? Also, any idea what the oil capacity is with oil filter? How cool, no water pump in the outdrive!
