lol!<br /><br />Can anyone tell me if the nuts that hold on a merc alpha are the same as the ones that hold on an OMC cobra? The omc ones are 7/16X20 thread. <br /><br />The ones I bought at the beginning of the year that were supposed to be stainless weren't and are now totally rusted, I want to get them off and get new ones before they're on there forever. Local dealer has merc nuts but wasn't sure if they would be the same, didn't know the thread off the top of his head. <br /><br />Thanks!

the threads are the same. the cobra nuts incorperated a washer in the nut the merc used a sepreate washer. if you must use the merc nuts use the merc washers<br /> good luck and keep posting

The boat is pretty dry, no smell at all. :) <br /><br />When I took my drive apart over the winter it had separate washers already. Guess someone switched over previously. <br /><br />Thanks!

older cobras had nuts and washers newer ones and volvo sx cobra drives use a nut/washer combo when installing nuts put a lubricant on threads to prevent galling omc/bombardier gasket sealing compound recommended

Here's a question, if I remove and replace the nuts one at a time will the gasket survive OK?
