These are new 23" or 25" diameter (at the base) pontoon boat tube nose cones. They can be cut down to fit smaller tubes and welded to the body of the tube to replace damaged cones. I also have used 23" wide x 25" tall u-shaped cones for the same price. Questions? Call Bill at 573-729-4617 or 573-247-3631. If I am outside, leave a message and I will call you back soonest. Thanks for looking, and... HAPPY BOATING!
