Hello. I purchased my first boat, a couple months ago. It is a 1977 Landau 24' pontoon. It has a trailer like nothing I have seen before. I am going to try to attach a picture here. It has a ripped sticker that says Taurus Pontoon Boat Trailer, and something Michigan. It has 2 axels. There is what looks like a bottle jack that has 2 metal bars that go all the way back to the axels. Can someone tell me what pumping this jack is supposed to do? It also has like a 6' tongue! It looks pretty old but it tows really nice. Any info someone might have, would be awesome. I googled Taurus boat trailer and nothing came up. I contacted Landau, they said they dont keep records that old. This trailer didnt have a VIN, I had to pay DMV to assign one.
