Could someone please provide the part numbers and dimensions of the 3 o-rings on a bravo input shaft? Thanks.

The parts charts at mercruiserparts.com list sizes for most of the o-rings in the drives,

Genuine Mercury & Mercruiser parts. BRAVO ONE

first making sure on the same page here as you - are you asking for O rings for when you re install the complete outdrive ?

If so, just buy the Bravo installation kit it comes with those O rings you are asking for and you do know you have to change the o rings gaskets on the bell housing to, when the drive is pulled ? the kit comes with all of that end to and is cheap in price - I have a ton of them.

going off the top of my head Merc part number 16755Q1 hopefully I got it correct the part number.

just a pic for reference

this O rings for the bravo input shaft ?

Have to ask why do you need the sizes of the O rings - Merc has the kit to buy with everything you need to reinstall the drive. There is more than 3 orings

Thanks fellas, I have the kits; just wanted to verify the sizes w my mic. Appreciate the help.
While we're on the subject; Perfect Seal is what most people are using for the o-rings and do I want to do a very thin skim coat on the whole mating surface? I dont like the non definitive results I've been reading..

skim coat ? of what

clean surface on the bell housing for the O ring gaskets then bellows adhesive to hold them in place ( back side of Oring only)

. O rings on the input Yoke shaft you grease them and Merc Extreme grease on those splines but not on the tip. Just full length of splines with the grease

gotcha. I knew about the grease but I'm glad you suggested the bellows adhesive; wasnt sure there. Out of curiosity what is the ideal application for Perfect Seal?

I was talking about the Perfect Seal but since I'm not using it then I guess its a mute point.
I've got bigger issues now anyway...
