Bought a new to me, but used 2005 Mercury 90 HP that did not come with an owners manual. Would have winterized it by draining lower unit and filling it. Then would have filled gas tank with enough Stabil for the size of gas tank. Next would have been to run it with water muffs and then disconnect the fuel and run it until it stalled. Lastly I would have removed spark plugs and added fogging oil and turn the motor over a few times.
The fuel line on this outfit is not equipped with a quick disconnect, it goes from a tank fitting to the fuel pump. So - running it out of fuel is going to be difficult unless I install some sort of fuel shut off in the line. When I questioned a Mercury dealer, they told me that all of the newer motors are rigged this way and that it does not matter if the fuel is run out of the carbs. Can't believe that this is true as the recommendation for decades was to run the fuel out before storage.
What is the correct procedure for winterization with the ethanol gas? In advance - thanks for your time, consideration and answers.
