Bravo sticks in forward
 

With 34 Bravo one props and a 1.36 gear, cone clutch seems to lock in forward so tight it's very difficult to pull out of gear. Does anyone have this problem or a fix for it??

Thanks, John B:confused:

check your cable adjustment

It is possible your cone clutch is slightly damaged and is getting jamb in the forward gear. The best thing is to have someone or yourself remove the unit and disassemble and inspect the shifter, clutch and the forward gear. If you have shifted the drive into farward at above 1200 rpm's you could have caused damage.

IMCO seems to think that the added low speed thrust of this combination which produces about a 10 mph idle speed, holds the cone in the the socket of the gear with a greater force than normal. When you try to manually pull it into neutral it's difficult to get it to release!

Thanks for the responses, but is anyone else had this problem?

1.36 gears and a 34" prop - sounds like a little much HP for a Bravo.:cool:

The boat is a 36 skater with 500 EFI's and runs 113 at 5600. What props and gears would you suggest?
Yes, it has modified rev limiters.
You are correct, but #6 drives are $75000.

I have noticed that mine is harder to shift out of gear since the Whipple install. I have 1.36 gears with (now) a Hydro 27 The idle is a tad higher also. The more load you put on it, the higher the shift effort. IF you find a solution, I too would be interested.

I just had that exact problem,
 

And I was told it was because the gears were not clocked correctly when installed. Ran it one weekend and ended up shifting it at the top of the idle surge (roots blower motor) several times because of the inability to get it out of gear when needed and sometimes going into reverse because so much force was used. Took it back to known good mechanic and found that clutch was now damaged. Never had this problem before. Have installed new clutch, but have not had a chance to try it yet....

Brad,
Let me know how it works.

Too much power for bravo drive

I think there are plenty of people running 500 HP's through Bravos on cats without to many problems.

Are both drives difficult to shift?

Have they always been difficult to shift?

The shift cables were checked and adjusted many times by a Mercury tech.

Shifting with over hub Mercury racing clevers was fair, Bravo ones aggrevated the situation, probably because they don't slip as much.

The port, which turns counterclockwise, is worse.

Does the B-Max have this problem with low ratios and high pitch props?? They still use cone clutch shifting mechanisims.

Thanks for the replys.

Did anyone read the IMCO SC article in Hot Boat last month?
They indicated they noticed this shifting difficulty and mey have improved the condition. They did some modification to the seating of the cone contact area!!
