Where does the cooling water exit? Should it come out the upper exhaust hole or down by the prop?
I’ve read where old outboards should use two cycle chainsaw oil instead of marine two cycle oils or synthetics. Can anybody tell me The correct oil and correct ratios? After perusing other threads I see there are many opinions. Where can I find the original ratios?
Thank you,

That is not an exhaust hole, it’s a cooling water exit, but because there is a thermostat that opens a bit as needed after warm up, you will see no water discharge initially and just a spray and steam later, but when it’s up and running wide open, you may see more of a stream along with the steam. The thermostat was added to get consistant idle at various water and air temperatures. There is no "tell-tale" water stream to tell you the water pump is pumping. To see if these OMC thermostat motors are cooling properly, I dip my hand in the water and flick some of it on the top of the engine block and heads – if it doesn’t pop/spit/boil, it’s cooling properly. It may sometimes boil when it hits the exhaust port cover.
