I currently have a 13 1/4 in diameter 17 in pitch prop on my 88 johnson. I found a great deal on a 13 3/8 in diameter 17 in pitch prop. Splines are the right number. 13. will this larger diameter affect anything ?
The larger prop diamere will not affect anything BUT: you must be sure that the hub diameter is the correct size for your gearcase. Measure your gearcase and ask about the hub size.
