Center Diameter for 12" Long x 3-3/4" Diameter Yates Keel Roller for Boat Trailers

Question:

I have a 1989 Larson All-American boat and trailer. I need to replace the rear keel roller. The current roller is 12 inches long. The outside diameter is 3 3/4 inch, and the middle diameter is 2.83 inches. There is no channel at the middle of our current roller. With the boat sitting on the keel roller, we do not have a lot of clearance between our boat and the read cross-frame. Can you tell me if this keel roller has a middle diameter close to 2.83 inches?

The center grooved diameter of the Yates Keel Roller for Boat Trailers # YR12244-125EC is 2-1/2" so your boat will be about 5/16" smaller than your current one, but keep in mind your boat is only going to be lower by a little more than 1/8" since your boat is only sitting on the top half of the roller.
