Hi all I have a 19.5 spectrum by blue fin with 3.0 mercruiser 1992. Wanted the know a few things. How do I change the oil and with what oil do I use? Can I use regular car oil? If so what viscosity and is synthetic preferable. Also have a alpha bravo stern drive.... Do I need to change the gear oil on a regular?
