Hi all. Im new to boating and have inherited a boat with a 1999? 50hp mariner .50 elpto. serial no OP040791. How would I get a manual and info on fuel mix etc. I looked online and think elpto means oil injected. I know its a 2-stroke but does oil injected mean it just takes raw petrol via the tank and oil seperately or what. Or is the oil serving another purpose? Thanks in advance.
