3 to 4 blade question.
 

i have a 22 ft pachanga with a 7.4 alpha. currently it has a 3 blade stainless apollo 15 1/4 21 pitch with a 4500 wot at 53 mph. i would like a better launch with a good cruising speed not so big on top end but its cool too. any 4 blade ideas would be great.

i had a 22pachanga,454/330 w /a bravo drive.stock blade was a 22p cleaver.i could get on the revlimerter @5200rpm at about 58mph.added good exhust,aftermarket intake,800double-pump,msd set up.i changed the prop to a 25pmarige and ran 65.3 on gps @5000rpm.hope this helps

Be careful on adding more bite to that engine / drive combination. Remember, they only offered it for one year for a reason. Adding more strain to a drive already right on the edge will be dicey at best.

On a related note, you might try posting over in the Props section and asking Brett at Bblades what he thinks. The guy is good.

thanks guys.
