Help with identifying stern exhaust ports on 08 Utopia with twin Rotax

[Headhunter]

Ok, before anyone comments, I did search all the stickys and how-to forums, and I could not find the detailed answer Im looking for......HA

I am bravely going to attempt wintering my Utopia SE this week for the first time myself. All the research I have found (and the manual) says to connect the hose adapter to the flushing adapter on the jet pump support. However I have two flushing adapters, one short and one longer, and both have threads for a hose adapter. There are two on each engine , a upper and lower one. Does anyone know which one I feed the antifreeze into and what the other one is called/For ?

Thanks in advance

First of all, I am in the same boat as you, in that I will be winterizing myself this year, and I have not had my 07 Utopia for very long. Like, not even two months.

I took a look at the stern, and yes, there are two threaded connections. I can find two pages in the O&M (pages 81 and 156) that show these nozzles, and for flushing both pages point to the upper connection.

Thanks alot. I must have a diff version, (downloaded) because mine only goes to pg. 128....... That really helps me. Does it happen to say anywhere what the lower one is for?

Congrats on the new boat.

Does it happen to say anywhere what the lower one is for?.

No, doesn't say anything. I'm hoping that a forum member with more knowledge than me confirms that it is the top connection...before I winterize in a month.
