Any water "resistance" spray will be gone within a week. I'm also thinking installing a ladder grease fitting for waterproof grease on the backside of the ladder maybe the only solution. I have to show my local Cobalt dealer an item I need (tower knobs) ...I guess I'll include the ladder.

Get lube for those knobs too

My 2004 220 ladder below (front). Ladder is very difficult to operate in & out, and as we know operates at or below the waterline. Hardware is also shot (one very special rubber shoulder washer, and 3 rubber washers). Looking for waterproof lubricant spray grease that will stick around for the season and not hurt the lake, if that's possible. The ladder is calling for help, suggest you check yours! Aside from a dealer, may have go to Grainer store and have the guy look at these washers. Probably will have buy a 100 to get 2. Diameter is important but thickness may be more important because of the mounting bracket. Another project for the winter.

Good information above. My 2005 ladder looks very similar to the one pictured above. Does anyone know the OEM for it? Bonus points if someone can point me in the direction of a three step version that extends a little deeper down.

I am also working on my ladder. Mcmaster Carr may have the insulating sleeve washers your looking for. I am going to measure what’s remaining of mine and try and come up with a match. I also need a new ladder rubber cover one of mine is at the bottom of deep creek lake.

Update: I lubricated the ladder by placing the waterproof grease on the piston part (part of the ladder that extends) and it goes up and down by hand "better". Its on my list to find, and improve, the washers. I'm thinking nylon hardware may be better then rubber. I showed the dealer the ladder and he shook his head. I wish I knew internally how the ladder worked. There's gotta be a spring in there that's in rough shape. Wish I could dissemble. Yes knowing the OEM would be nice but since there no name/label/seal I have a feeling it a 100% a Cobalt design.

If anyone discovers ladder hardware please post P/N's and source. thanks

I’m looking at oil impregnated bronze as a solution to the washers. I may have to machine to the correct size but they should last longer and wear better.

Nice solution. Would you be able to post pics of that Daniel?

not sure if it was mentioned... but slideruleracer has good info on a fix for the ladder.
