What size bolt for a Bravo3

[agallant80]

I lost one of the bolts when I was putting my Bravo3 back on. Does anyone know the part number or what size and where I should get one from?

I can't edit this for some reason. Not the bolt but the nut that is used to attach the drive to the bellhousing.

Ayuh,... I believe you'll find the 6 nuts that hold the drive to the gimbal are 7/16" fine threaded chrome plated brass ny-locks,....

Thank you. Those little suckers are $3 each for the OEM merc stuff....

Ayuh,... I ain't sayin' ya can't use SSteel, but it galls, 'n pulls the threads quite easily,...

That's why Merc uses the copper/ brass, chrome plated,....

When I installed my Bravo transom mount, I had to replace all the (thru-transom) studs with new ones because the were a bit corroded and the threads were a little beat up!!

They don't have to be very tight either. I also put a couple of these on my drive and one on the propset! [7/16"-20 threads]

Good to know, I'll look in to that
