I'm running a 25p mirage with 9% slip. would a 24p bravo give more slip or less

Single or twin? If a single I would think a 4 blade prop wood give better performance on a 29' boat. I'd try both a Merc Bravo and a Merc Rev 4...

Pondering this myself...I keep blowing out my 3 blades at speed now with the new engines.

Hey Capt, whats your setup. Boat, hp, props, how deep is your prop shaft

Hey Pat,,, running twin SB makin 400hp 425tq. spin a 23p mirage+ 5400, a 25p mirage 5000.... prop shaft is 7 3/8 deep... looking to put -2 Imco.

More blade surface area usually means less slip. From 3 to 4 blades of the same diameter should be less slip.

If switching to a Bravo 1, go up in size one pitch. They tend to be over-rated. A 26p Bravo should keep you in the same rpm range as the 25p Mirage. I had to find this out the hard way. I'm running a 30p Bravo 1 with 1.5 gears and I doubt I could pull a 30p in any other prop. I think you should try one. The shorty worked great on my boat and if you do that you will almost certainly need four blades. I don't know how the shorty will work on a 29' boat though as you will lose bow lift due to less leverage (higher prop).

I have twin 400 HP 383s, Mirage Plus 23s. Not sure on X dimension. Keep getting over speed on port when I start to trim out.

Thanks thirdchild, I will try a pair of 26,s. I have a friend with some. The boat does ride nice in the water. Did your -3 Imco bolt up to a Bravo1

Yes it bolts right up. Mine is -2".
