Got a dumb question here... Just bought my first boat (always used Dad's boats until now) and was prepping for the first trip this weekend by cranking the engine to make sure everything was working. Of course, I hooked up the muff to the water intake on the lower unit prior to ignition, but became concerned when I did not see the water stream coming out of the top of the engine so I shut it off so as not to overheat. I probably ran for 5 to 7 seconds before turning it off. I didn't have a temp. alarm, I was just being cautious. So, my question is, does or should the water come out in a stream from the top of the engine when flushing (as it does when in the water) and if so, how long should it take after the engine is started before it starts coming out? Thanks for your help.
