Converting PM300's to 25"
 

I am in the process of converting a pair of 1999 Merc ProMax 300's with Sportmaster gearcases from 20 to 25". I have all the parts to do this except the longer studs which attach the lower unit to the mid section with the spacer in between. BAM cant help - Merc hasent answered - HELP!

The two studs BAM sells are M12 x 183 - millimeters - which is 7.2" in length and I am assuming 12 threads per centimeter. The other one is M10 x 173 which is (I think) 6.8" long. I need the longer one (I think) but looking at their pics they specify the M10 nut for the Sportmaster.....HELP!

Thanks, TJ
