Our center walk through portion of our windshield leaked like crazy due to all the seals being dried up. Last year I tried re-sealing the top window and sealing shut the vent with silicone from the outside - while it was significantly better, it still leaked. This spring I went through the process of identifying all of the required seals - this took hours on the phone with TaylorMade and two separate shipments. I hope this post saves someone the aggravation I went through!
First things first (and this was the source of a LOT of the trouble), FourWinns has the wrong part number listed on their parts website for the center portion of the windshield. They list the fixed part number and not the hinged one - the seals are different.
On the FourWinns site - FourWinns part number 060-0927 / TaylorMade # 576-901405 (this is a fixed center window)
It should be - FourWinns part number 060-9023 / TaylorMade # 576-805405 (this is the hinged center window)
When you order from TaylorMade, the good thing is you can buy all the seals independently, the bad thing is you have to buy all the seals independently. This takes considerable time as their BoM's don't seem to be terribly complete. Here is the list of seals required:
8224950 x 2 feet (top glass, bottom seal)
8359000 x 2 feet (top glass, top seal)
8233980 x 4 feet (top glass, side seals)
8229900 x 2 feet (vent hinge cover)
8351000 x 2 feet (vent glass, bottom seal)
8352000 x 3 feet (vent glass, side seals
4911000 x 5 feet (goes behind the vent glass seals)
8288940 x 2 feet (walk through, door to boat seal)
51013 x 25 feet (windshield frame to boat seal)
All in, should run around $200. I used a clear roofing sealant to seal all the metal to metal corners and metal to seal joints. It was Lucas Universal Terpolymer Sealant. The only parts I didn't replace were where vent hardware goes through the glass - they need replacing but they sent me the wrong parts so i just put sealant on them. So far, just a slight drip in extremely heavy rain where one screw comes through the glass, a bit more sealant should fix that. Now I don't have to put paint trays on my dash when I leave the boat!
The above parts will seal up the center window - I also got new wire cover (rubber strip along the inside top of the windshield frame) and new rubber to replace the horrible looking foam screw cover on the outside bottom of the windshield. The new screw cover looks a lot better than the shrunken foam.
