I have a 1979 Yukon Delta houseboat and need information on the toilet and septic system.  Specifically, how do I drain out the sewage?  Is there a pump with a switch?  Where would it be located?

There were Yukons ranging in size from 23 feet to 38
feet. I have 2 in my collection. I sold my 3rd that was 23 feet in length. I now have a 25 3/4 and 31 3/4

Francis and Bud Mills owned the co. he died in 2002 and a relative wanted to restart the company, but nothing came of it.
The last Yukon built, that I know of, was 1996.

If you are interested I have the largest known collection of Yukon Delta sales brochures and instruction sheets. A lot of work went into restoring torn, missing sections, water destroyed and worn areas (3 to make one good brochure), with many hours of work until they are a nicely presented work.I have a refaced copy of the floor plan for the 31 3/4 and 25 3/4 foot Yukon $3.00 each; They have the interior layout, a detailed depiction of layers and weights of fiberglass as well as upper deck thickness and what it was fabricated in; I have the refaced/restored copy of the brochure for the 1982 Yukon...$12.00. This shows interior pictures, exterior pictures descriptions and offerings in the 25 3/4 and 31 3/4 Yukons; Both the black and white floor plans and the color brochure show the flybridge.; A lot of work went into restoring torn and worn areas to a nicely presented work. There are no shop manuals or wiring manuals available. I just finished a 40 plus page VP book that really goes into the color coded wiring. If you need the Volvo Penta stern drive repair manual 1968-91 by Seloc...I have it on CD...$11.00... I add to this collection all the time...should you need more!!
Good luck on your work.
