The Volvos seem much harder to fill up and get pumpin' than others. The Volvos have a drain hole on the bottom of the out drive. The engine will probably never fill up unless you plug the hole. If you look at the "Volvo-Specific" earmuffs in the West Marine catalog, you will notice that there is a plug attached by a cord to the earmuffs. That plug is for the hole. because my plug is long gone, I use a cork. Just don't forget to take it out.
