hi all,<br /><br />i have a 1981 johnson 9.9hp. i over torqued and twisted one of the 6 bolts that hold the lower unit to the exhaust housing. i'm looking for the part number for these bolts (and a place to purchase) and also i'm wondering how unsafe it is to run the motor with only 5 of them installed for the time being.<br /><br />i'm assuming these are not regular steel bolts, correct? <br /><br />thanks,<br /><br />matt
