Hello,<br /><br />I have a 99 Johnson 90 Hp with a alluminum 3 blade omc 14 x 17 prop on it and reach around 5700 rpm at wot on a 17ft RIB.<br /><br />The boat goes on plane ok and the holeshot is ok but I am always looking for better 
<br /><br />now I am thinking of getting another prop in SST and found a stiletto 4 blade 13 1/4 x 17 prop.<br /><br />Can somebody tell me if I have to change anything to run the 4 blade instead of the 3 bade prop ? Or can I just take the 3 blade of and slap the 4 blade on and go boating ?<br /><br />And what kind of advantage/disatvantage will I experience with this new prop on it ?<br /><br />Thank you in advance,<br />Stef
