Bravo 3 drive gear ratio

MIKES342

Is there an easy way to determine what the gear ration is for a 2013 bravo three on a 260.  Just would like to know.  I have contacted my dealer and we are waiting for  a 21 pitch prop set.  I currently have a 22 pitch prop set.  My problem is with full fuel,  water and 4 people on board it struggles to get on plane.  Oh yes it as a genny and radar arch as well.  Oh yes and a VC bottom paint.  With the 22 inch prop my wot is 4700-4800 rpms. I feel the 21 inch prop and so  does Rinker will get me to where I need to be and decrease my time to plane.  Oh I was wanting the gear ration so I could use the prop selector on the mercruiser web page just to see what it suggested

Is ther a way to check this by using the serial number.  I can't see the number while the boat is in the water.  Or is there a comon gear ratio for a 6..2 liter bravo 3.  For a 260 EC

the 2.2:1 ratio is pretty common. I would guess the s/n would ID it too if you check with Mercury

I got it when I put the boat on the trailer today.  It was 2.20,  I also got an education on removing and installing a bravo 3 prop set.  I had to remove the front nut with and impact gun.

 

Thanks everyone for your information
