Hi Dan, If they are the same as the three holes on the rear of a one piece exhaust plate ( the bit the powerhead bolts to ) ( thats technical speak) 1 1/2" 7/16 UNC I think.

It's the same length and size as the s/s bolt that holds the anode on a Bravo 1 gearcasing. Probably not that helpful, but they sure look nicer than a nut and stud!

The thread is 7/16th UNC, and I'd use a 2" bolt if your set up is like mine, as shown in the photo. Mine is a 5 hole mounting, but I haven't fitted the other 2 bolts yet.

If your exhaust is the newer type, with a 4 hole fixing, you'll be able to use slightly shorter bolts, although the correct was is to use a 2" stud, unc one end, unf the other! according to Mayfair.
