A friend recently gave me a stainless prop to run<br />on my 97 25hp Mariner....he sold his boat w/25hp merc.<br />The ss prop is a 14 pitch.....the aluminum prop<br />that I took off is a 13 pitch.<br /><br />It runs great at wot....it just runs rough when in<br />gear at idle. Also when you first give it some<br />gas it hesitates just a little. Other than that<br />it runs great. Maybe it needs to be idled up a <br />little because of the extra drag of the 14pitch?<br /><br />Thanks,<br />Wily

Did you find any difference in top speed with the 2 props given the different pitch? What is the WOT rpm with each?

Dunno.....it is only a 25m model. No gages, speedo, tach or anything. <br /><br />Wily
