93 fountain 27 with a 502 mag carb motor all stock what should i be running for a prop any ideas? right now 23 p mirage 3 blade 60mph at 5k rpm

my buddy runs a 24 bravo1 (4 blade)

Try a 23P hydro left

hey what are your buddies seeing for mph with those props , was wondering about trying a 4 blade also can not get it to do it but every once and awhile if i am up on plane slow down to 15 mph and then get back on it the prop will spin out meaning rev but will not go ? will not do it often any ideas thanks

I have a 2000 fountain 27', 502 mag mpi, 1.5 ratio B1. The boat came with a hydromotive 15 1/5 x 23 pitch LEFT HAND rotation prop. The boat ran 68 on gps at 4950 rpm's. I contacted BBlades and talked to him about other props for more speed, good cruise and good out of the hole. He recommended a Bravo 1, 24 pitch LEFT HAND rotation, labbed by him. He said it would get me on plane fast, have good cruise speed and put me at 70-71 mph at 5150 rpm's. I sent him the bravo 1 and let him lab it. From what he told me about how this prop would perform, HE WAS DEAD ON THE MONEY. The boat jumps on plane, great cruise speed and runs 72 mph on gps at 5150 rpm's with 3 people on the boat, a little more than 3/4 tank of fuel and a light chop on the water. I also have a 2004 fountain, 29' with a 500hp, 1.5 xr drive. This boat came with a bravo 1 RIGHT HAND rotation prop. The boat listed to port side when getting on plane and while running. The boat ran 70 mph. I contacted BBlades again and he recommended a hydro 5 blade LEFT HAND ROTATION. I purchased 1 of these props and BINGO, the perfect setup again and the boat does not list to port anymore and it runs 75 mph. From what I have read, fountains with single engines like left hand rotation props. I would recommend that you contact BBlades. He is very easy to talk to, but have all of your specs written down (engine, drive ratio, cruise speed/rpm, wot speed/rpm) because he will want to know exactly what you have. Sorry to have been long winded with my story but I hope this helps you.

I agree w/ speedfever, call BBlades, he'll hook you up.

I'm turning a Labbed 23P Hydro 4 blade Left rotation. I can bang the rev limiter if the conditions are just right. 99' 502 MAG. I'm going to try the 24 Bravo and see what happens.
