???
i have a 33 avance with tripple 300 x/s i just tried a pair of 28 bravo on out side and a 26 bravo center. the motors are turning outward. fact are 5000 rpm on outside motors 28B and 6100 center motor 26 B at Neutral Trim .
THE BOAT WAS LAYING OVER TO THE RIGHT.
I KNOW PUT THE OUTSIDE DRIVES TURNING INTO THE CENTER . I WILL CHECK AND SEE HOW IT RUNS.

PROBLEMS 1 HANGING OVER TO THE RIGHT???
2 OUT SIDE MOTORS TO LOW RPMS .

SOLUTION 1 TURN MOTORS INWARD.
SOLUTION 2 REPITCH 28 TO 27.5 AND LAB FINISH SO MY RPM GO UP. CENTER MOTOR REPITCH TO 26.5 LAB A HOLE LOT.

????????????

I had a 32 Skater with triple 300x's and used outboard cleavers with a lot of success - none of the problem you mention. Why are you using Bravo style props?

Gregg Reichman

You need to get the motors turning mid 6000's. Labbing Bravo's can add 300 rpm to their current rpm.

Shooting from the hip it looks loke 24 B1's Labbed on the outside and Lab the 26 in the center.

We run Bravo 1 props on 3litre motors all the time. Sometimes we put vent holes in the prop for better planning.

I just can't get this garbage wright.

MY BOAT IS GOING SLOWER WITH THE 300X/S STROKERS THAN WITH 250 S.

AS I SAID BEFORE MY CENTER MOTORS IS CAVATING AT TOP END . IT GOES TO 7000 RPM OVERREVS. I HAVE PUT 28B1 IN THE CENTER MOTOR AND IT KEEPS OVERREVING.

BACK TO SQUARE ONE
I PUT MY OLD SETUP BACK TO WHAT USE TO RUN BEFORE WHEN I HAD THE 250 S WITH 25 MIRAGE P AND RAN 72 AND MOTORS HOOKED UP. WITH THISSETUP THAT RAN GREAT WITH 250 I WAS ONLY ABLE TO GO 63 AND OUT THE SIDE MOTORS WOULD NOT GO OVER 5000 RPM AND THE CENTER MOTOR REV ALL THEWAY TO 7000 RPM..

WHAT A FU... HEADACHE I WISH I STILL HAD MY 250

THESE 3.2 STROKER SUCK MERCURY SHOULD KNOW...

any one mercury bblades throttle up maybe

my boat has a 26 degree v if that helps..

i had the same problem the 300xs is a engine build for light boats and sucks on the heavy boats!! the 250 runs much better

that really sucks ...
