I have two props and don't know much about them other than the markings on them and they are both nautique factory props. One is marked 13.5 X 16 VR and the other is 14 18P. I have a 2001 SAN and was wondering which one would be better for my boat. I mainly wake board with two or three people in the boat and have factory ballast. The 13.5 X 16 VR is the prop that came with the boat but it has much damage.

Pitch is the second number listed in the propeller description. The 16 pitch should give you more low end power. the 18 would be better top end. The first number is diameter.
here is some good information: http://www.deltaprop.com/anatomy.aspCurrent: 2001 Air Nautique GT-40 -
Which boat?
The 13.5 x 16 is probably an 536, the 14 x 18 is probably the original OJ? The 536 is a good choice, should have plenty of power behind a GT-40, may need a bit less prop if it's behind a Excalibur.Comment
