What would a set of 26p 4 blade bravos do for the performance of my 311? Right now im turning 5100 rpm with 25p 3 blades and i see a steedy 68 and the best ive seen is 71. The power i have in the boat is merc 420s and trs drives. Im not particularly looking for top speed but thats always a plus, but if it increased my cruising speed would be even better. Thanks for the input.

You may want to borrow a set to try, because adding pitch AND another blade may cost you more rpm than you will like. The diameter will be smaller so that will help some..... but try before you buy!!!!

I have a buddy that has a set that i can borrow. I was just asking to see, so kinda know what to expect.

I guess since no one is doing it that i should stay away.

sounds like your just about right where your at .... If you can borrow a set why not try them and see ....I would think better cruise but lost top end ...bigger wheels could be tougher on the drives too ..........m

If you have TRS Drives they tend not to like 4 blades.

The four blades are pretty good.
You can stay on plane at a much lower RPM.
They make the boat run real stable.
You come out of the hole quicker.
But you will loose some top speed.
Try your buddies out that will tell you if you can gain.
I tried a set on my 292 and lost five miles per hour top end.
NOW WE CAN'T HAVE THAT!!
Good luck post your findings if you test them.

or ...... I would try a set of 24 B1's

Could you elaborate a little more?

I gues there is only one way to find out and that is to just try them. Now the only problem is getting a hold of them. When i try them ill post back. Thanks for the imput.

What he is getting at is a TRS 80's Formula has the drives so deep in the water that it takes alotof power to turn a 4 blade that deep.

What about standard 25 mirage+ 3 blades?

Look up Bret At BBlades .... He helped me out with my 311 ... I told him what i was trying to accomplish and he gave a couple of ideas .... matter of fact he went as far as lending me the props I needed to try until I got the right ones all I was charged was shipping and when bought them it was taken off the bill. You can't lose with him.

He has 25+ yrs of Mercury R&D background then went out on his own.
Great customer service!

Good Luck !!!

I have a Bravo1 28" pitch 4 blade brand new for sale if anybody needs one,cheap

After this weekend i know exactly what he is talking about. I couldn't turn those 26's past 3600 rpm and getting up on plan took me for ever. My cruising speed was up a few mph, so need less to say ill be putting my 25 back on.
