I think your motor likely has an air cooled powerhead with a water cooled leg. If that is the case, use air cooled two stroke oil. Minimum 16/1. Might have a rubber impeller, but I would bet propeller pressure fed. A little disasembly will certainly tell you. You can guess based on if there is a tube behind the propellor to pick up water or not. Cowling removal can be tricky. Just go gently and don’t force it.
