Hey Sturtz and Welcome.... Never looked at the "n" prop... I take it the "n" stands for
narrow?? It looks that way on the web site, but hard to tell... Besides welcoming you
I was hoping that you would tell us(me) the size difference from the 14x4W...
Not much help on what it will do[]... But if you have it on and it spools up faster,
you have the true to life tester... Let us know how it goes... Have you ever tried a
13x4W?? seems like your 72 may like that better than the 14x4w, maybe even the
12.25x3.75... I ran that in my YS 63 during the "Hot" season here... It would over
rev if you let it, but hardly ever at full throttle on the "Do"...But WoW on the response!!
It worked great for me....
