I have a 1989 3.7 L Mercruiser that I want to change the oil in but can’t find the drain plug. Please enlighten me.
Thanks
Mark
 
If there isn't a hose connected to the drain plug. Your best to suck it out through the dipstick tube. They sell vacuum oil suckers at most marine places. If there is a hose connected to the drain plug. You'll have to fish it out through the hull drain hole. Make sure you run the engine so the oil is hot. Otherwise you'll be there for hours waiting for it to drain
