Prop Clearance

The prop that is on my boat now is an OJ 14x18. There is 1 inch of clearance between the bottom of the prop and the prop protector on the trailer. If I upgrade my prop with the 14.25 x 14.5 would that be considered to close? What does everyone consider to close and what clearanes do you have now?

I understand exactly what you are saying. I measured from the beam directly under the prop. Tomorrow I will go out and check it the way you are saying. I thought about this because I remembered your post earlier about the OJ prop being to close on your trailer. Thanks
