My 305 Conquest has twin Verado 250 hp engines. While getting them ready for Summer, I was trying to run them out of the water.I have the hose attachment device on the lower unit, where the water enters. However, as the engine runs, with water on, I don't see the stream of water that should be coming out of the lower cowl. I didn't run them for long, so they don't overheat. I didn't see a stream of water in either engine, while running. Any suggestions? Thanks

That's a flushing system "ONLY" do not run your motor using that system. You could damage the motor doing this use the muffs if your going to run it out of water!Tom |

I should have been more clear on this, Tom. I did use the "muff" device, at the bottom side of the gearcase, in front of the propeller. This is the normal water inlet while the engine runs in the water. (The engine flush connector is by the powerhead). It is from the normal water inlet that no stream of water is coming out. |

Let me clear up that last sentence.With the motor running, and the hose attached with the "muff" onto the lower unit, I still get no water stream that usually comes out of the powerhead area while the motor runs. I can't believe that I am having such a hard time asking this question.....please bear with me. Hank |

Attach the hose to the fresh water flushing connector just under the engine cowl. After turning the water own you should see a stream of water coming from the pee hole. Not y our fault I misread what you asked. The fresh water flushing system is the way to go that way there is no need to crank the engine unless you just want to run it.Tom |

However, if you do want to use the ear muffs on the lower unit AND run the motor, I would mention to you three things:1. If motor was not recently running (i.e. just pulled from ramp), when you flush on muffs, you might be waiting awhile for Thermostats to open up at the required temp. 2. I have noticed a very minor delay when flushing my 200HP OPTI on muffs. I attribute this to feeding through a larger motor's coolant system. We are talking 30 seconds here, but still takes longer than my old 60HP, which was a far smaller motor. 3. Get dual feed ear muffs for larger HP motor, not the basic one that feeds water from hose only on one side. I prefer NOT to use the cowling flushing port with motor not running. |

"I prefer NOT to use the cowling flushing port with motor not running."Mambo: Don't you mean with the motor running? My boat in in my back yard. I want to run the motor, with water going through it before I have the dealer tow it to the launch ramp........where I will take it to my slip. I want to make sure it runs OK. That way I don't look like a fool, with the boat in the water at the ramp, and one of the engines don't start.

Mercury makes muffs expressly for the Verado. You need to use these.Regular muffs do not cover the nose cone holes- special muffs for verado by merc: Here is the flush attachment & cover for the front pick up holes. FLUSH ATTACHMENT PART # 44357T2 FLUSH SEAL KIT DUAL WATER PICK UP PART # 881150K1 Go to veradoclub.com they have all the answers. Tom |

HenryK - you NEVER use the cowling flush port with motor running. That's for water flushing with motor OFF. I did not realize the Verado has the water intakes on the nosecone. Lesson learned. Thx Bluewater. I knew the Pro XS optis and racing motors did. You will require the special nosecone attachment for running water. Concur Verado Club best source for that motor. |
