I'm getting ready to pull the outdrive on my '96 SeaSwirl with a 4.3L VolvoPenta setup. It has a Cobra labeled outdrive that is actually the Volvo SX unit.<br /><br />The previous owner has installed a smooth stainless collar around one of the outdrive bolts. This is intended to keep someone from walking away with the outdrive apparently.<br /><br />I've not found the key nor been able to find the previous owner. <br /><br />I'd really like to avoid taking a chisel to this part (or any part) of the boat.<br /><br />Any hints?<br /><br />Thanks,<br /><br /> johnbo
