proper prop size ???

[georgiaboy]

I have a 2005 Triton 175 aluminum bass boat with a 90 hp Johnson motor. the prop that came on the boat is a 14" with a 21" pitch 13 count pline. All I can find is a 13 1/4" 21" pitch. What difference do you spectulate this will make in my preformance? also where can I get a 14" 21pitch? the boat now runs about 5400 rpm and 55 mph. It is a wonderful boat so i do not want to do anything to change the preformance significantly.

13 1/4" x 21 pitch may result in an increase of 100 to 150 RPM and in all likelyhood, no change in your speed and performance. You should be fine.
