It was made by Mercury. It is a 2 stroke.
I use 32:1 royal purple synthetic oil in mine. I think it is formulated to NOT burn so it lubricates but doesn't coke-up & foul your plugs after long periods of idling. I also run this mix in old McCulloch & Bendix air cooled motors along with the old Mercury "K" series. There have been no "issues" related to the fuel mix since I changed from (I thought)cheaper oil. The oil was cheaper but the seized McCulloch air cooled outboard motor greatly offset the savings on the cheaper oil. I don't personally care what you choose to use and offer my opinion and recommendation based on positive personal experience.
Here's one more

I'm guessing the powerhead is like a Mark 20 & the gear-case too(if it is FNR) or like a KG7 if it is forward only. The bore may be slightly smaller than a Mk20. The Wizards usually had smaller carbs & fewer reeds to choke off the hi-rev HP so as not to compete with the Mercury cousins. They idle exceptionally well & will out-troll many others.
Most anyone would recommend changing the impeller before use. At least test it before you get into trouble out on the lake.
it is forward only. i've had it runnin in a trash can full of water, and it seems to like the higher end better than idle. i noticed two set screws, one for idle and the other says high speed. i have the high speed set about a quarter turn away from all the way down and kinda set the idle where it ran the best.
If it runs well & cool in the can, you should be fine on the lake. Have any back-up power?
I'm a collector so I usually take at least 2 outboards to the lake to test and fine-tune under actual load and just to enjoy the ride. I haven't ever had to paddle back to the dock even though I've had some engine failures over the years.
