Your first Osprey maintained chronic leads on those windows. I finally took them off and to an auto glass place to have the gasket material replaced. We searched high and low and could not find something that would work. Talked about just bedding them in goo, but wasn't sure we could get them bedded flush to the frame, where they would stay put. After checking on replacements with Bob (no joy...different design), I made new windows out of 1/4" Lexan and through bolted them on, similar to the surface mount windows now being used. Wood frames on the inside as backing material, although that is probably not needed. Just cleans up the look. I bedded one in silicone and another in a special sealing tape a friend had (they make the stuff). Both have held and have not leaded a drop. Bob said to use Polysulfide, but all your plastic folks say to use nothing but silicone. I used black and it looks like a custom made gasket material. For the bolts, I used cup washers on the outside. Looks good and is no longer leaking. Howard On Oct 16, 2006, at 2:39 PM, Thomas Howe wrote:
Has anyone replaced the plexiglass windows on a M-17? Are there any particular issues that need to be addressed? Silicone Vs. Polysulfide for gasketing? Fasteners? Particular bevel to the window? I have a persistant leak through a cracked screw hole on my boat, and I don't want to just slather goo on top of it. Any and all suggestions will be considered and appreciated.
