Trying to figure out the model of my cousins GTS. He wants to get a better performing prop and I ordered a wear ring for it already but we're not sure of the model. Difficult to read the number on the back. Looks like 5551 to me but I can't tell for sure. Some have 140mm pumps and some have 155mm (?) How do you tell which one you have?? Also.... what might be a good prop for his ski ??
