Prop Identification & Selection

[msstring]

Novice here looking for help on prop ID and selection. Below is a link to a picture of the two props I have. With either one I am having trouble getting up on plane. The numbers don't seem to correspond to the typical Diameter/ Pitch. So I am hoping someone here can help me identify them so I can determine what I should change.
It wouldn't let me upload the picture so hopefully this link will work.

Otherwise the numbers stamped on the hubs are:
2​​​​75 15
293 12.5

Some prop mfgrs. stamp the pitch on the prop somewhere, or the pitch is easily read from the part number, sometimes just a number and sometimes followed by a P. Sometimes, you get both D and P. My hip shot would be that you have a 15 and 12.5 but props usually come in even or odd increments, seldom in sequential incriments....but I have a Mercury Laser II that doesn't follow that practice.

If you have a prop shop nearby, drop by and have them check it for you. They can also allow you to test props before you buy to get what works for you. But if your problem is something else, no prop will fix it to suit you. (opinion)
