I now have a second Hydrodyne to go with my '71 20 foot skier; a '78 18 foot. The new boat's fundamentals look like it was well cared for so the restoration part has involved light work so far. I do have a couple of parts questions: I have been unable to find the windscreen/deck seal of the proper size. Taylor's 846500 seems to be the only one readily available and it is much larger then the original. Has anyone found a suitable replacement? The second issue is a broken roller arm on the interrupt switch. After learning that the system was redesigned with the roller arm switch no longer available I finally located a use one on eBay. Has anyone found a source for just the arm and roller assembly? Thanks.
