I broke both the starter bolts off my 2000 mercruiser 3.0L. I got the inner, closest to block, bolt out no problem with a drill. The outer bolt is giving me fits!1 I can't access from above and have tried evrything from drilling to an extraction bit, but no luck.
3.0 Mercruiser Engine Starter
When upgrading/converting from the SAE hole size old Direct Drive/Beer Can starter (3/8”) to the metric hole size PMGR starter (10mm), the bolts must be changed out to the conversion bolts that have metric shanks and SAE threads, and are made to make the final alignment and lock. Replacing the longer hole DD starter with the shorter hole PMGR starter will cause additional free space. DO NOT
stack washers on the bolts to fill up this space as it prevents the features of the bolt from functioning properly. The starter mesh will not be correct and the starter may shift slightly on the mount. This is not only for marine applications, but all Delco pad mount starters. While some of the marine applications have OEM special bolt heads (12 point and smaller than normal hex bolt heads) making them easier to manuever tools into the tight spaces, the 9/16 hex is a normal OEM design bolt head (or metric similar 15mm). If this unit is not installed properly, the warranty may be voided and returns denied
If you need the conversion bolts, please indicated so in the drop down menu before adding the item in your cart, and we will ship those along with the starter.
