    Default Speedometer on 2004 Sunsport Not Working

    I noticed the other day on the lake that my two speedometers were not working at all. I have a 2004 Supra Sunsport 21V. Spent a lot of time looking for pivot tubs, water lines to unclog; etc. I finally figured out that the Sunsport 21 V drive has the speedometer built into the depth finder in what is called a multi-sensor Triducer. Near the V-Drive there is a Airmar Thru-hull Retractable Triducer that sits in a tube that accesses the bottom of the boat hull. When I got under neath the boat I located where this tube comes out near the water intake opening. I noticed that the paddle wheel extends below the boat and was broken off the bottom of the triducer. I first thought I would have to buy a whole new Triducer Multi-sensor unitfor $200. I learned that I could go online and by a Replacement Paddle Wheel Kit. $17.95 and I am now back up and running.

    The multisensor Airmar is a DST800-N2000
    The paddle wheel kit part number is 33-398-04
    Ignore the number on the cap of 20-459-01. this is not the part number.

    The folks at Blue Heron Marine shipped it to me in 3 days.

    My speedos are out too. Haven't checked the paddle wheel but I hope this is all that's wrong with mine. Thanks for the thread!

    Is this what I need for a 2006 20V, or did they change the triducer at all?
