Fellas, I need to know the bolt sizes for the three bolts that will fit a flywheel puller for a 1965 Merc 39 (3.9 HP). I work with a machine shop, and I forgot to measure the threads/dia. last night. From my recollection, they look something like a 1/4 ish size, but I don't know the thread pitch either.<br /><br />If no one knows, if you at least can tell me if they are metric or US, I'll know what types of bolts to get.<br /><br />Thanks in advance!!<br /><br />P S - If no one answers before 11 am today, don't worry about it, I'll check over the weekend and get the bolts on Monday. I just wanted to play with it over the weekend...<br /><br />Ron<br /><br />Ron

Hi SeaDawg,<br /> I believe they're 1/4"-28 tpi. If the holes are 5/16" then they would be a fine-thread (24, I think).<br />- Scott
