There is no such thing as a "stock size" prop. They are matched to the boat at the time of sale, based on load and intended use. If you don't see any numbers on the prop, then you will need to remove it to see them.

Re: does anyone know what prop is used

I think you are a little confused about how prop recomendations work. Based on the information you have provided, unless someone on here just happens to have the exact same boat with the same power, you will never get anything more valuable than the WAG of 17-19" pitch offered above.

It all start with the prop you have now, you have to get the numbers off of it, nobody here can do that for you. Then we need to know what your current WOT numbers are and what you are trying to accomplish with the new prop.

Props are not like tires, there is no book/chart that says Xboat with Yengine uses Zprop. A 17" prop from one manufacturer might perform similarly to a 19" prop from another manufacturer, making generic suggestions, just that, generic.

Go to the turning point site and punch in your info. and it will give you an idea what to use. If you look on the hub of your prop it should have some numbers on it usally the last number will be the pitch of the prop hope this helps......
