I wasn't sure what you meant for a minute on the hose part. I think you mean if the mufflers (hose) is on, then with it being forced to have cool water flowing, it won't overheat???
And, yes, the alarm came on as soon as I turned the key on, and not always after I started it. Other times, it just came on. Sometimes it wouldn't come on till I tilt/trimmed the motor. Then, as I was leaving finally, it didn't come on at all.
But that was about 1-2 AM, and by then I was whooped and not sure.
You all mention wires. Is there a simple wiring schematic and description available anywhere on the Internet??
Just so you all know, I live in the Springfield area in Illinois BUT the boat is currently in storage at Lake Shelbyville which is nearly 75 miles one way and takes 90 or so minutes to get to....
UPDATE WITH QUESTION:
What is the purpose of the two cycle oil mix. Can the motor run for awhile without?
What happens if I put oil into gas tank but the motor is still mixing the oil BUT keeps setting off the beep??)
