I'm going to be doing some maintenance to my motor which is an '89 260hp 5.7 Mercruiser with Alpha One gen 1 outdrive.
Basically what I need to know is what oil should i be running and what oil filter, and what spark plugs are needed.
I'm really struggling to find much info on these older motors. I tried a search but saw many different opinions.
Any help would be greatly appreciated (I am trying to stick with OEM specs on oil weight, etc.)
Thanks, Matt
