The side window seals on our 5788 have shrunk with age. None of them are leaking, but cosmetically they look shabby and could do with tidying up or replacing. (These are on the fixed windows not the sliders)

I searched everywhere for the seal profile material without success, and am now considering the second option of filling the gaps with some sort of sealant. Does anyone have any suggestions of the product to use?

The same sealing strips are around the windshield where there are also gaps, but unlike the seals of our M490, these seals are a different profile and have become very hard.

Any help would be appreciated

Hi Rob, I got a 100 feet of the seal couple years ago. Derrick put me on it and I believe I got it from Lake Union Sea Ray.

If for some reason that's not correct let me know at This email address is being protected from spambots. You need JavaScript enabled to view it. and I'll go back and find the email contact when I get to my office and get it right. Or Derrick may chime in and correct me.

Hi Brian
Thanks for the suggestion - I also thought this might have been the answer, but the seal for the 4788/490 is a different profile. (the guys in our marina had some that I tried, but no luck).

Rob,

Try CR Lawrence and see if they have it. They have tons of those (that's where I got some of mine). The trick will be finding the right profile of the seal for the 52/57.

Another option is calling the guys at Lake Union Sea Ray and having them call Bayliner for you and getting you the part number.

Good luck

Derek

Post a pick if you can, If it's the one i'm thinking of I have about 100 ft at work, if not I can have it made, (kind of a 1/4 moon with a notch on top?)
I've had quite a few different sizes made for Bayliner customers Thanks Doug

blue tape off corners, use sikaflex-715. less hassle than replacing seals, will adhere to seal and if your good it is clean looking.

There is a thread on this subject. Particularly the extraction of the old and insertion of the new.
Do not forget to make the water relief cuts in the new track inserts in the correct places. In constant or heavy rain they will fill and overflow.
On the 4588, there is a molded gutter at the base of the window frame on the interior to catch the overflow if it happens. This molded channel runs out beyond the rear slider frame and lets any collected water flow out. My boat had these exits caulked over causing the collected water to flow down and on the floor and carpet eventually saturating the carpet at the salon slide entry door.

I gave up searching for the side window seals, and decided to try Sikaflex as a gap filler. I now know for sure that I'll never be a glazier!

I chemical cleaned the area, blue taped it, had my PTFE coated scraper at the ready and the result looks like crap. It's a good job that I only tried one of the gaps. I am now searching for rubber sealing strip again.

I managed to take a photo of the end profile of a piece of the rubber, and having it pulled out of the frame, it does look a lot like the windshield rubber seals on the 4788/490's. The photo pictures a 45 degree cut, and the face you see when inserted is the lower one facing down and left.



Any help on locating this seal rubber would be appreciated as I need lots of this stuff to do the side windows and the windshield

Rob are you sure it's not the same as the windshield stuff on 47/49? I think I have some left over from when I did my windshields. If so, I'd be happy to send you some to try.

Hi Derek - thanks for the offer, I'd like to take you up on that and would be happy to pay for it.
How can we get to pick it up to try?
