Am I right In guessing that the dash switch is only to set the gauge to read from one tank or the other to show the fill level and the ‘dial’ is to actually select which tank to feed the motor from?They don’t have anything to do with each other, do they? Meaning if the dial is set to port and the switch to starboard it won’t mean anything other than the motor is drawing from the port tank while I’m watching the level on the starboard tank, right?
not true, the impeller is driven by the drive shaft directly from the motor. It sits on the top of the lower unit before the actual foot. the prop is driven by the set of gears inside the lu that turn the prop shaft, the 2 are totally separate from each other. I believe what you're prob seeing is on some plumbing on some motors the thermostats have to open up before you see the tell tail (pee stream) peeing. On some motors on some years the tell tail is plumbed on a by pass so it pees as soon as the motor starts

@pprice01 Some motors won't pee well using muffs. I had an outboard here in my yard on a boat that I was helping someone sell. It was a 40 HP Yamaha.Start it up with muffs and not a drop of water would come out the pee hole. Stick the motor in a barrel full of water and it would pee up a storm.Not sure if that's also the case with your outboard or not, but I thought it was worth mentioning. Maybe someone else will have more feedback on this.By the way, nice looking boat! Really love that color scheme, and it looks like it's in decent shape.Oh, and do my eyes deceive me, or is that a paper graph on the console??

It wouldn't hurt to do a post-purchase routine that includes preventative change of the thermostats and water pump impeller just to ensure all is good for you.
