I've looked through a lot of documents online but can't find anything about the two ports with the arrows pointed at?
What is the function of both of them as I though the exhaust gasses were supposed to go out around the propeller...
I ran the engine in a barrel for an hour and there is a little smoke/ steam from the top port, the port doesn't get hot but if you block both of them for a few seconds then the bubbles come out from the vent over the prop over the cavitation plate
How much smoke/ steam is ok? Should it have gone away after she heated up?
Sorry for all the questions :-(
